Some aquarists report their crabs getting used to them and losing their fear after a while. However, if you ever have to handle your red claw crab for any reason don’t forget that they will still pinch hard enough to startle you!

Red claw crabs can be found in most aquarium stores. Contrary to what most fishkeepers assume, they are not fully aquatic and actually need access to land. A rectangular paludarium of at least around 15 gallons (54L) will keep your red claw crabs much happier than a regular aquarium. The aquatic part should be at a salinity of around 1.005 and a water level of at least 6 inch (~15cm); add a small filter and heater to keep the water clean and warm.

The scientific name is Sesarma Bidens, commonly called Red Claw Crabs, Red Clawed Crabs, and Mini Crabs. The red clawed crab is very good for the aquarium because of their ability to clean or scavenge all the uneaten food in the tank. They seem to get along with fish in the tanks as long as they are fed. In general, the red clawed crabs keep to themselves and are peaceful.As with other crabs, it is imperative that the red clawed crab is given dry land to climb on and be able to breathe air. The Under Water Island series provided by Atlantis Under Water islands offer habitats that sit on the bottom of the aquarium and supply dry land and fresh air. The crabs will go in and out of the biosphere at the crabs’ leisure. The crab homes also have a feeder tube that allows a person to put shrimp pellets, tubiflex worms and even live crickets into the habitat from the top of the aquarium.Red Clawed Crab
Maximum Size: 2”
Aggression: High
Temperature: Water temp 75-80 F
pH: 7.5-8.5
Hardness: 15-25 dH
Brackish Tolerance: 1.003-1.010
Minimum Tank Size: 10 gallons
Feeding: Will eat basically any foods provided. Dry foods and meaty foods like shellfish and fish should make up majority of diet, should supplement with green foods occasionally (like peas, cucumber, aquarium plant clippings)
Notes: Like many of the “freshwater” crabs available in the aquarium trade, the Red Clawed Crab is actually a brackish, amphibious animal. They cannot survive completely submerged on a long term basis and require the ability to exit the water. The best tank set up for these crabs is a paludarium-type tank that is at least 50% land (where Red Clawed Crabs spend the majority of their time).Special breeding requirements will not likely be met in the home aquarium. Larva of The Red Claw Crab live for a time as Plankton in the water column. The ideal environment may vary from crab to crab, but it is important to remember that you offer dry land for the red clawed crabs. In their natural environment, red clawed crabs can spend as much time out of water as in the water. If you don’t have your aquarium drained of some water with a rock sticking out of the water, you can place an Under Water Island in the aquarium, which will provide fresh air and dry land. Red clawed crabs are a little shyer than other crabs, so it is good to offer plenty of obstacles in the aquarium. When an Under Water Island is used, the red clawed crab will most likely live or spend all their time around the biosphere. The red clawed crabs like hiding by the entry way in the Under Water Lagoon model. Although red clawed crabs are mostly peaceful, they love catching and eating crickets. This can be done using the feeder tube and an Under Water Island. Catching the food seems to help them be happier and healthier.Red-clawed crabs (Perisesarma bidens, formerly Sesarma bidens) are often sold as "freshwater" crabs, but really do their best in brackish water. They are widespread in Asia, where they dwell in costal mangrove swamps. They can survive in full saltwater and freshwater, but do their best in a brackish aquarium.
