2. Fiddler Crab
Violinists are quite small and generally do not grow more than 5 cm. They are incredibly eye-catching. A claw is proportional to the body of the crab, small and delicate. However, the other claw stands out and is dramatically larger than the other. This oversized claw also has bright colors, often light yellow or gold in color.

For a diet, these crabs like to eat plants and animals. You can eat small fish and salty insects. For plants, they enjoy dried seaweed and fresh or dried fruits and vegetables.
Thai devil crabs also need an area in their tank where they can rest on land. Be sure to include a sandy area with plenty of hiding places and burial places for them. They always like to appear underwater, so it is definitely a necessity for them.
4. Vampire Crabs
Vampire crabs are a very fun way to keep. They are also quite rare and probably more difficult to find than other types of freshwater crabs. They are available in a variety of colors, usually in rich shades of orange, purple, or red.
The terrifying-sounding name comes from the fact that they have unique yellow eyes, sometimes called “bright”. If you were expecting a bloodsucking crustacean, sorry for the disappointment.

5. Gold Claw Crabs
Golden claw crabs are some of the most unique crabs you can add to your aquarium.
These crabs are so named because they have a very large “golden” claw. It’s not exactly a golden color, but it’s pretty close.
It is also important to understand that these crabs, like most crabs, can escape very well from tanks. They can scale almost anything, including hoses and pipes, and are known to sneak frequently. Be sure to secure your lid every time you open it for feeding or cleaning.
6. Thai Micro Crab
The Thai micro crab is sometimes known as a fake spider crab. These names are apt because this species is incredibly small. They are about 1 centimeter in diameter (less than half an inch!).
They are usually brown or gray in color with long spindle-shaped legs, similar to a real spider. They are also covered in very small hair, which helps them collect food that floats in the water.
Thai micro crabs are very sensitive to changes in water conditions.
Because they are so small and fragile, they cannot cope much with a predatory neighbor. That is why it is important to keep them in tanks with the most docile companions.
Small invertebrates can often live peacefully with Thai micro crabs. Some types of small fish can also live well with them.
Micro crabs are not very sociable and can spend much of the day in hiding.
Aquarium crabs are known to escape from enclosures. If they are so small, the risk is even greater.
Take extra precautions to make sure there are no small openings in your tank that can serve as an escape route for a stubborn crab.
7. Panther Crabs
Finally, we have the panther crab. Panther crabs are a popular choice due to their beautiful markings. They are bright orange with black spots, hence the name.
Panther crabs are generally very friendly crabs, but they become aggressive if not properly fed. It is important that your panther crab (and really every pet) is fed on time and in the correct amount. If not, these crabs will surely attack and eat slower fish.
Panther crabs can also escape very well. You should make sure your tank has a tight fitting cap to reduce the chances of leakage.
While giving them a good place to rest from the water is important, you don’t want them to walk around your house.
How do I care for crabs in an aquarium?
Many new aquarium enthusiasts avoid getting crabs for their tanks. They are concerned that they are too difficult to maintain.
Caring for freshwater aquarium crabs is no more difficult than caring for a fish.
As with any pet, you must provide the basic needs for it to thrive. This includes a good environment in which they can grow and live their whole lives.

Add decorations like sticks, rocks, and moss so your crabs can go up and down. It’s also a good idea to set up a shielded network so that your friends don’t accidentally escape.
Fill the aquarium, but leave an area where your crabs can sit out of the water. This is good for them to rest, dig and dig.
Most of the crabs are omnivores. Therefore, feed your crabs in a balanced way with plants and animals. It is a good idea to keep your diet fresh for them.
When you first get your crab, it can take a while to learn what it likes to eat and what it doesn’t touch. You should try swapping some ingredients or swapping foods you don’t like.
Best Freshwater aquarium crabs can eat protein-based granules or algae. They also enjoy meat like flies, bloodworms, and small salty fish. Include vegetables with steamed vegetables in smaller pieces in your diet.
