Appearance

Physical characteristics of a gorilla crab

Size and weight

The gorilla crab is a relatively large crab when compared to some other aquarium species.

On average, an adult gorilla crab can grow to be around 4 inches wide, with a body height of approximately 2 inches.

However, in rare cases, it can grow larger, with some specimens reaching up to 6 inches wide. In terms of weight, it is a heavy crab, with an average weight of around 5 ounces.

It is essential to consider the size and weight of the gorilla crab when selecting an aquarium, as this crab requires a sizable tank to accommodate its size and ensure a healthy living environment.

Color and pattern


The gorilla crab gets its name from the dense hair-like spines and velvety texture covering its entire body.

The color of this crab varies depending on its habitat and mood. It can range from a light sandy-brown to a deep chocolate-brown, with some individuals having reddish hues.

The hair-like spines covering the body can be a lighter color than the body, giving it a unique stripped appearance.

Additionally, the legs and claws feature white or yellow bands, adding to its distinctive look.

It is crucial to note that the gorilla crab undergoes a natural molting cycle (crab molts), and during this phase, it may appear paler as it sheds its old exoskeleton, which can sometimes alarm aquarium owners.

Claws and legs


The gorilla crab has two large front claws that are powerful and sturdy, which it uses to catch and crush its prey. The smaller, more slender claws are used to bring food to its mouth, and for cleaning its body.

The claws themselves have a brownish tip or yellowish-white color, with brown stripes or dots on the top.

Unlike other crab species, the gorilla crab has visibly longer legs, allowing it to move with ease around the aquarium.

The legs are also covered in small hair-like spines that match the rest of the body. The entire physical makeup of the gorilla crab is specialized to its scavenging and feeding habits, giving it a unique role in the saltwater tank ecosystem.

Physical characteristics of an emerald crab

Size and weight

The emerald crab is much smaller in size than the gorilla crab, making it a popular option for aquarium owners with limited tank space.

Adults are typically only around 2 inches in width, with a body height of approximately 1 inch. In terms of weight, these crabs are relatively lightweight, with the average adult weighing no more than 1 ounce.

The small size of the emerald crab makes it ideal for nano reef tanks or corner reef tank and smaller aquarium setups. Its lack of noticeable weight also allows for a broader range of tank glass thickness and style without stressing the structural integrity of the equipment.

Color and pattern

The emerald crab is named after its vibrant emerald green color. The color is most striking on the legs and carapace, with a hard exoskeleton that has a variegated pattern that gives off a shimmering effect.

The legs and claws are hairless, with two small pincers that have a yellowish color. Their underside is also typically paler than the top.

Emerald crabs have a unique coloration and pattern that makes them distinct from other aquarium crabs. Their green hue is not found in every marine species, which makes them an attractive addition to aquascapes.

Claws and legs

The emerald crab's legs and claws are relatively tiny compared to those of other crabs of comparable size.

They have two small pincers in the front for grabbing food and cleaning their shells. The emerald crab's claws are not as large and powerful as other crab species, which means it does not have the same predatory behavior as the gorilla crab.

Instead, it is a scavenger that feeds on the leftover food from other marine different species, such as anemones, coral, and fish.

The legs of the emerald crab are slim and can move quickly which makes them adept at navigating around the tank in search of food.

This distinct physical structure of the emerald crab makes it an excellent addition to tanks where other species may be prey.

Comparison between the two crabs

Differences in appearance

While both the emerald crab and gorilla crabs are intriguing to look at, they have some noticeable differences in appearance.

Firstly, the color and pattern of both these crabs are starkly different. The gorilla crab has a darker brown color, while the emerald crab is a striking green.

Secondly, while the gorilla crab has a large, hairy body with visibly longer legs, the emerald crab has smaller limbs and a smooth, slender appearance.

Thirdly, their claws are also distinct; the gorilla crab has two large and powerful claws for catching prey, whereas the emerald crab has small pincers.

These differences in appearance are important to consider when deciding which species is the best addition to the aquarium.

Similarities in appearance

Despite their distinct differences in appearance, there are also some similarities between the gorilla crab and the emerald crab.

Both crabs have a hardened exoskeleton covering their bodies, which serves to protect them from predators.

They also have small, two-parted eyes, which allows them to see moving objects and predators effectively.

Additionally, both crabs have 10 legs, and their unique external features make them visually striking and distinct from other marine species.

While there are some noticeable differences in appearance between these two species, their shared physical characteristics make them equally unique and worth considering as aquarium pets.

Habitat

Natural habitat of a gorilla crab

Geographic location

The gorilla crab is a species of marine crab that is found primarily in the waters of the Eastern Pacific Ocean.

Its natural range stretches along the western coast of North America, from Mexico (also in gulf of Mexico) up to Vancouver Island, Canada. They are most commonly found in tidal pools or rocky coastlines, which provides them with the necessary protection and shelter.

Gorilla crabs typically inhabit warm, shallow water ranges, with temperatures between 70- and 80-degrees Fahrenheit.

In the wild, they are scavengers:

  • feeding on various plants,

  • macro algae,

  • bubble algae,

  • hair algae,

  • coralline algae

  • and small invertebrates like nassarius snails and worms (bristle worms and fire worms)

  • and sessile invertebrates (attached to the reef also in your reef aquarium)

- therefore it is important to provide enough algae along with additional creatures feeding on them.

Understanding the natural habitat and diet of this species is crucial to providing them with similar living conditions within the aquarium use.


Water temperature and depth (water column)

Along with the geographic location, water temperature and depth are essential factors to consider when discussing the natural habitat of the gorilla crab.

As mentioned, these crabs thrive in warm, shallow waters with temperatures ranging between 70- and 80-degrees Fahrenheit. They naturally live in an intertidal zone, which means they can tolerate a wide range of salinities as well.

Typically, the depth at which they are found does not exceed 100 feet (water column), making them more of a shoreline species.

Therefore, replicating these temperature and depth ranges within an aquarium is necessary to ensure a healthy living environment for these crabs.

Maintaining proper water temperature and salinity within the correct depth range will promote natural behavior and survival.

Natural predators

The natural environment of the gorilla crab is also influenced by several predators, which has adapted this crab to be particularly elusive and savvy.

Dark tips: natural predators of the gorilla crab include

  • sea otters,

  • octopuses,

  • and some larger fish species (keep them with small fish)

Beyond this, the gorilla crab's tough and hairy exterior offers it natural protection against smaller predators like crabs or shrimp.

In the wild, these crabs have also been observed burrowing in rocky crevices or hiding under rocks to evade predators.

In a captive large aquarium environment, ensuring shelter or burrowing spaces is crucial to recreating a natural habitat and reducing stress caused by the sight of other fish tanks' inhabitants.

It is also essential to ensure that the gorilla crab is paired with suitable tank mates- species that cannot cause significant harm to the crab.


Natural habitat of an emerald crab

Geographic location

The emerald crab is a unique species found in the tropical and temperate waters of the Atlantic Ocean, Pacific Ocean and Indian Ocean.

They typically inhabit reefs and prefer shallow, warm and sheltered areas with plenty of live rock (pounds of live rock) for grazing on algae, sponges and other small invertebrates.

These crabs are one of the few reef species that can survive in very low oxygen levels, which makes them ideally suited to environments such as mangroves or estuaries.

As they naturally inhabit shallow waters, they are more commonly seen closer to shorelines with warmer ocean temperatures than most other deep sea specimens.

Water temperature and depth

The emerald crab is found in depths ranging from a few inches to over fifty feet, but it is mostly seen near the surface.

These crabs prefer warmer water temperatures, with the range optimal for their natural state being between 73-83 degrees Fahrenheit.

They will occasionally venture down into deeper waters, provided there are food sources available and that the temperature remains within their preferred range.

The emerald crab also prefers to inhabit areas with large amounts of rocks, coral, sps corals, soft corals, coral polyps as this provides them protection from predators as well as providing them with plenty of grazing opportunities.

Yes, I Want It Now

Natural predators

The emerald crab does not have many natural predators in its native environment, as it is well protected by its spiny shells and its ability to hide among rocks and coral (that is why it is important to provide plenty of rocks in you aquarium as these crabs got hiding among them in their gens).

Its main threats come from larger crabs, which may try to scavenge for food that the emerald crab has already collected (they are really great scavengers).

Other known predators of the emerald crab include some species of ray fish, barracuda and occasionally octopus, though they are rarely seen preying on this particular species.

Comparison between the two crabs

Differences in habitat

There are several key differences between the emerald crab and its close relative, the sally lightfoot crab.

Despite both species living in warm temperate waters, the sally lightfoot is more tolerant to extreme temperatures, allowing it to inhabit shallower waters than the emerald crab.

Furthermore, while both species are found among rocks and coral, the sally lightfoot crab prefers areas with fewer obstacles and more open terrain.

As a result, it can often be seen scurrying along beaches or intertidal zones rather than deep-sea reefs like its cousin.

Similarities in habitat

Despite the many differences in their environment preferences, the emerald crab and the sally lightfoot crab have some notable similarities.

For instance, both species are scavengers that feast primarily on decaying matter such as seaweed, providing them with a plentiful source of food.

Additionally, coral reefs are favored by both species due to their abundant availability of small prey and algae.

Finally, they both possess strong claws which allow them to cling to surfaces while they search for food and protect themselves from predators.

Behavior

Feeding habits of a gorilla crab

Diet and food sources

Gorilla crabs are omnivorous and feed on a variety of food sources.

Their diet includes a variety of plant matter, such as leaves, shoots, and stems; small animals like insects and worms; and carrion.

As they creep along the seafloor, they can find plenty of these nourishing items to keep them fed. In addition to this, they will sometimes scavenge sea anemones or other small creatures if the opportunity arises.

Feeding behavior and strategies

When it comes to feeding behavior, gorilla crabs show different strategies in order to acquire food. They are known to hunt small animals with their claws as well as scavenge for carrion.

Additionally, they display a unique ability to dig and burrow in search of food sources that may not be visible from the surface.

When consuming plant matter, they typically rip and tear the leaves or stems off with their claws before crushing and crushing them up into smaller pieces (tips of the claws are really hard).

In rare cases, they are also known to use leaf-cutter tools like those used by some primates.

Feeding habits of an emerald crab

Diet and food sources

Emerald crabs are scavengers that feed on a variety of food sources, including bits of algae, small animals like worms and crustaceans, carrion, and decaying detritus.

They will also scavenge for sea anemones or other small organisms if the opportunity arises.

Unlike some other marine creatures, emerald crabs are not picky eaters and will consume whatever is available to them.

This makes them opportunistic feeders and they often scour the seafloor in search of food.

Feeding behavior and strategies

When it comes to emerald crab feeding behavior, they primarily rely on scavenging and search for food in small crevices or cracks in rocks.

They are also known to use their chelae (claws) to probe the substrate and uncover food sources that may be hidden from view.

In addition, emerald crabs will often take advantage of various current patterns in the ocean to locate food sources.

By allowing themselves to drift with the currents, they can effectively cover large areas of ocean floors in a short amount of time and thus increase their chances of discovering potential meals.

Comparison between the two crabs

Differences in behavior

The two species of crabs, the emerald crab and the porcelain crab, show marked differences in behavior. Emerald crabs are much more active and opportunistic feeders than their porcelain counterparts.

This is due to the fact that emeralds are scavengers that search for food, while porcelains prefer to wait in one place and filter feed plankton from the water.

Emerald crabs also have better eyesight, allowing them to spot prey more easily than their porcelain cousins.

They are also more agile swimmers, making them better equipped to capture food items with their chelae (claws).

Similarities in behavior

Although the emerald crab and porcelain crab show differences in behavior, there are also some similarities.

Both species actively seek out food sources from their environment and use their chelae to capture prey.

They also both have poor vision when compared to other aquatic creatures, though emerald crabs have better vision than porcelains.

Additionally, both species can remain camouflaged in their environment to avoid predators, and they exhibit a strong homing instinct that enables them to find their way back home after foraging.

Compatibility with Other Marine Life

Interaction of gorilla crab with other marine life

Aggressive behavior

Gorilla crabs are known for their aggressive behavior towards other marine life (thus the name after lowland gorillas)

They will often bite, pinch, or grapple with other creatures in order to protect themselves or defend their territory.

This aggression is usually exhibited against members of the same species, but it can also be directed at other marine organisms if they feel threatened. In some cases, gorilla crabs have even been known to attack humans in aquariums or when underwater diving.


Suitable tank mates

As a pet owner and avid marine life enthusiast, I have spent countless hours observing the interaction of my beloved gorilla crab with other creatures in its tank.

While these crabs may appear ferocious, I have found that they can actually be quite social with the right tank mates.

Some suitable companions for the gorilla crab include

  • snails,

  • shrimp like mysis shrimp or mantis shrimp

  • and smaller fish such as clownfish or gobies.

Snails are especially beneficial as they help keep the tank clean, while shrimp provide a unique visual contrast and don't usually interfere with the crab's territory.

When introducing any new tank mate, it's important to carefully monitor their behavior for any signs of aggression or territorial disputes.

Trust me, finding the perfect complement for your gorilla crab will enhance the overall beauty and balance of your marine ecosystem. It is also important not to allow your tank to become as so called mature tank with a lot of gunk in filter and substrate.


Unsuitable tank mates

When it comes to choosing tank mates for your gorilla crab, not all marine life is suitable.

While some creatures may seem like good idea and a good fit at first glance, they can actually be quite dangerous or disruptive to the overall balance of your aquarium.

It's important to avoid adding

  • any fish that are too large or aggressive as these could easily overpower and harm the gorilla crab.

Great addition - many species of fish

  • such as cichlids and angelfish have been known to nip at the claws of crabs which can cause serious injury or even death in extreme cases.

Other unsuitable tank mates include

  • eels,

  • octopuses,

  • sea stars,

  • and predatory crustaceans such as lobsters and hermit crabs.

Finally, you should also avoid

  • introducing any invertebrates that require high levels of oxygen since this could create an unhealthy environment for both the crab and its tankmates.

By carefully selecting compatible companions for your gorilla crab you can ensure a safe and enjoyable experience for everyone involved!

Interaction of emerald crab with other marine life

Aggressive behavior

The emerald crab is a small, yet feisty member of the crustacean family. Although appearing quite harmless in appearance and size, it can be surprisingly aggressive when provoked or threatened.

Similar to its cousin the gorilla crab, it will often bite, pinch, or grapple with other marine life in order to protect itself and its territory.

This aggressive behavior can be especially prominent in younger emerald crabs as they are more likely to lash out at perceived threats.

Additionally, emerald crabs may become territorial if there are multiple individuals living in the same tank or habitat.

In these cases, they will establish dominance over their environment by defending their food sources and turf from other creatures.

In extreme cases, emerald crabs have even been known to attack humans while underwater diving or in an aquarium setting!

This is why it's important for pet owners and aquarists alike to be aware of this species' propensity for aggression and take appropriate measures when placing them into a tank with other creatures.

Comparison between the two crabs

The emerald crab and the scarlet hermit crab, while both belonging to the same family of crustaceans, have very different behaviors when it comes to interacting with other marine life.

The emerald crab tends to be more aggressive and territorial, defending its territory from perceived threats and attacking humans in some cases.

This behavior is especially prominent in younger specimens who are more likely to lash out at perceived threats.

In contrast, the scarlet hermit crab is generally much more peaceful and docile, displaying little aggression towards potential intruders or tank mates.

The emerald crab will also become territorial if there are multiple individuals living in the same tank or habitat.

However it is not overly aggressive towards its own species so groups of two or more individuals can often coexist peacefully as long as they have ample food resources available.

In comparison, scarlet hermit crabs are highly social creatures that prefer living in small groups and will even form a hierarchical structure where one individual takes on a dominant role within the group.

In terms of tank mates, both species should be kept away from eels, octopuses, sea stars and predatory crustaceans such as lobsters due to their potential for aggression or disruption.

However, suitable companions for the emerald crab include snails, shrimp, smaller fish such as clownfish or gobies and other crustaceans such as hermit crabs.

While suitable companions for the scarlet hermit crab include mollusks like snails and clams as well as algae eating invertebrates like starfish, sea cucumbers and folks like cleaner shrimp and other species useful for cleaning.

Overall, there are several key differences between these two types of crabs when it comes to their behaviors involving interactions with other marine life that pet owners must consider when deciding which one is right for their aquarium ecosystem.

Differences in interaction with other marine life

The emerald crab and the scarlet hermit crab, while both belonging to the same family of crustaceans, differ significantly when it comes to their interactions with other marine life.

The emerald crab is more aggressive and territorial, defending its territory against perceived threats and attacking humans when necessary.

This behavior is more pronounced in younger specimens, who are more likely to lash out at potential threats.

The scarlet hermit crab is much more docile and peaceful, displaying little aggression towards others or possible tank mates.

The emerald crab may also become territorial when there are multiple individuals living in the same tank or habitat; although it isn't overly aggressive towards its own species so groups of two or more can often coexist peacefully provided there are sufficient food resources available for all.

On the flip side, scarlet hermit crabs prefer living in small groups and will even form a hierarchical structure where one individual takes on a dominant role within their group.

When it comes to selecting compatible tank mates for either species, eels, octopuses, sea stars and predatory crustaceans such as lobsters should all be avoided due to their potential for aggression or disruption of the aquarium's ecosystem balance.

Suitable companions for the emerald crab include

  • snails,

  • shrimps like brine shrimp,

  • smaller fish such as clownfish or gobies

  • and other crustaceans like hermit crabs;

while

  • mollusks like snails and clams

  • as well as algae-eating invertebrates like sea cucumbers

should be considered for inclusion into an environment that houses a scarlet hermit crab.

In conclusion, pet owners must carefully consider which type of crab they wish to add to their aquarium ecosystem based on their behaviors pertaining to interacting with other marine life.

Both species should be kept away from potentially dangerous creatures but suitable companions can provide an enriching experience for everyone involved if carefully selected based on compatibility factors like size and temperament.

Similarities in interaction with other marine life

Despite their differences in aggression levels and preferred living conditions, both emerald and scarlet hermit crabs have several similarities when it comes to interacting with other marine life.

Both species should be kept away from

  • eels,

  • octopuses,

  • sea stars

  • and predatory crustaceans such as lobsters

due to their potential for aggression or disruption of the aquarium's ecosystem balance.


In terms of suitable tank mates for either species, smaller fish such as clownfish or gobies are ideal companions that provide enriching experiences for all involved.

They provide a safe environment for the crabs while providing entertainment and exercise through swimming behaviors.

Additionally, snails, shrimp, and other crustaceans like hermit crabs can also serve as compatible tank mates since they require similar water parameters and diets as the two crab species discussed here.

Additionally, mollusks like snails and clams as well as algae-eating invertebrates like starfish and sea cucumbers should be considered for inclusion into an environment that houses either an emerald or scarlet hermit crab.

The presence of these creatures not only adds variety to the aquarium but also helps keep the water clean by consuming microorganisms which could otherwise lead to disease outbreaks in both the crustaceans and fish living there.

In summary, both emerald crabs and scarlet hermit crabs have several similarities when it comes to interacting with other marine life; however pet owners must take into consideration each species' individual personalities before deciding on suitable tank mates for them.

Careful selection is key for creating a harmonious environment where all inhabitants can thrive without risk of disruption or aggression from one another.

A variety of foods should be provided, such as small pieces of raw shrimp or mussel, small pieces of seaweed, frozen foods, and dried pellets or flakes specifically formulated for hermit crabs.

Depending on the size of your crab, these items can range from pinhead-sized to about half an inch in length.

The food should also be supplemented with calcium supplements such as crushed oyster shells or cuttlebone to ensure proper crab growth and development.

Feeding frequency will depend on several factors such as the size of your crab, the amount of food they consume, and the type of food you are providing them with.

In general, feeding once per day should suffice; however if you notice that your pet is still hungry after eating then you may want to adjust the feeding schedule accordingly.

Additionally, when it comes to fresh seafood make sure they are thoroughly cooked before feeding them to your pet to avoid any potential health risks.

Acclimatization and quarantine

Acclimatization and quarantine are essential when introducing a new gorilla crab to an existing tank or starting an entirely new tank.

When introducing your pet to the aquarium, it is important to make sure that they have been properly quarantined for at least two weeks prior to being placed in their new home.

This will help ensure that any potential illnesses, parasites, or diseases don’t spread throughout the entire aquarium environment.

Additionally, acclimating them slowly is key so as not to shock their system and cause stress.

This can be done by gradually increasing the salinity level of the water in their quarantine tank until it matches that of the main tank.

Once everything has had time to adjust and you are sure that your pet is healthy, you can add them safely into their new home.

Monitoring your pet for signs of stress above all else will help you determine if they have successfully acclimated or not, as well as how well they are handling their transition into a new environment.

If signs of stress persist then you may want to consider a different approach or even additional steps such as providing hiding spots and additional food sources to help alleviate anxiety and promote a happy, healthy lifestyle!

  • a large enough tank - at least 20 gallon tank and maintain high-quality water parameters

  • such as temperature (72-78°F),

  • pH (8.1-8.4)

  • and salinity (1.020 - 1.025).

Additionally, regular partial water changes are necessary to keep nitrate levels low which will help prevent disease from developing in your tank environment.

You should also make sure that there are plenty of hiding places available for your pet so they feel safe and secure while living in their new home!

Feeding and frequency

When it comes to feeding an emerald crab, it is important to provide them with a variety of different foods that are specifically formulated for hermit crabs.

These can include small pieces of raw shrimp or mussel, small pieces of seaweed, frozen foods, and dried pellets or flakes.

Depending on the size of your crab, these items should range from pinhead-sized to about half an inch in length.

Additionally, their diet should be supplemented with calcium supplements such as crushed oyster shells or cuttlebone in order to ensure proper growth and development.

How often you feed your pet will depend on several factors including the size of your crab, the amount they consume at each meal, and the type of food being provided.

It is generally recommended to feed them once per day; however if you notice that your pet is still hungry after eating then you may want to adjust their feeding schedule accordingly.

  • or cooked grains

which can offer nutritional benefits and help keep their diet varied and interesting!

Acclimatization and quarantine

Acclimatizing and quarantining an emerald crab is an important part of keeping them as a pet, as it helps to ensure the health and safety of both your pet and existing tank inhabitants.

Quarantine tanks should be separate from the main tank, and the water needs to be prepared with slightly different parameters such as a higher salinity level - around 1.024-1.026 SG.

In order to acclimate your crab properly, start by introducing them slowly into their quarantine tank, giving them time to adjust to any changes in temperature or salinity.

During this time, watch for signs of stress such as slow movements or loss of appetite.

If you observe any signs of distress, it may be necessary to reduce the rate at which you are acclimating your crab in order to prevent further damage to their health.

Before adding an emerald crab into the main tank, it is also recommended that you observe their behavior in quarantine for 7-14 days to ensure they do not have any infections or parasites that could spread throughout the entire aquarium environment.

Additionally, if there are other crabs in the main tank then it is also important to quarantine any new introductions so that diseases or parasites don't spread between individuals.

Once everything has had time to adjust and you are sure that your pet is healthy, you can add them safely and confidently into their new home!

Comparison between the two crabs

Differences in care and maintenance

The care and maintenance of an Emerald Crab differs from that of other hermit crabs. Generally, Emerald Crabs are considered to be more sensitive to their environment, with specific needs for temperature, pH and salinity.

Temperature should range from 72-78°F, while pH should remain around 8.1-8.4 and salinity 1.020 - 1.025.

Regular partial water changes are necessary to maintain nitrate levels, as well as provide plenty of hiding spots for the crab to feel safe and secure.

In terms of feeding, Emerald Crabs benefit from a varied diet including small pieces of raw shrimp or mussel, seaweed, frozen foods, and dried pellets or flakes (depending on size).

Calcium supplements such as crushed oyster shells or cuttlebone must also be added in order to ensure proper growth and development.

Feeding frequency depends on how much food is consumed at each meal; usually once per day is recommended but can be adjusted if needed based on the crab's hunger level after each meal.

Fresh seafood must always be cooked before being fed to prevent potential health risks.

Finally, it is important to acclimatize and quarantine any new Emerald Crabs before introducing them into the main tank; a separate quarantine tank with slightly higher salinity is best (1.024-1.026 SG).

During this time watch for signs of stress such as slow movements or loss of appetite and adjust acclimatization rate accordingly if necessary.

It's also important to quarantine any new introductions between existing crabs in the main tank in order to prevent the spread of disease or parasites between individuals.

Once everything has had time to adjust and you are sure that your pet is healthy they can then safely join their new home!


Similarities in care and maintenance

Despite their differences, Emerald Crabs have much in common with other hermit crabs when it comes to care and maintenance.

Other very interesting crabs for you to consider

In a saltwater tank, there are various types of crabs, some of which are more popular than others.

The gorilla crab, emerald crab, and

  • pom pom crab

are some of the favorite crabs that many enthusiasts like to have in their tanks.

Although they are harmless filter feeders,

  • the hitchhiker crab,

  • jonah crab,

  • and stone crab

are not as popular due to their size and aggression towards other tank mates.

Additionally

  • the arrow crab,

  • mithrax crabs,

  • pom pom crabs (with pom poms)

  • decorator crab,

  • and xanthid crabs

are also lovely additions to a saltwater tank due to their unique features and symbiotic relationship with macroalgae and live rock hitchhikers.

However, these crabs can have a higher price range, depending on the species and size.

The mithrax crab (mithraculus sculptus) or emerald crab, for example, is common in the aquarium trade, and one can find them at their local fish store - the price ranges of $10-$20 depending also on size (little crab vs adult crab).

The gestation period of each type of crab also varies, with some like the pom pom crab having shorter gestation periods than others.

Despite their differences, every particular crab has its unique qualities that make them interesting and beautiful in their right.
