Habitat
The recommended tank size for housing is a minimum of 10 gallons. A 10-gallon aquarium can keep 1 male with up to 2 females; however there is still a chance of confrontation that could end in a fatal fight. A sandy substrate is ideal to allow for easy foraging and to facilitate burrowing habits. Several hiding places should be provided; the use of driftwood, aquarium décor, and aquatic plants are ideal. Despite what many hobbyists may say, Red Claw Crabs are not fully aquatic and must have access to land. This can be done by having a half-land-half-water style aquarium set-up, or by having aquarium decorations that are taller than the water line.These crabs are excellent climbers and great escape artists. Therefore, the water line should be at least a few inches below the rim of the tank, and a tightly fitting, fully sealed lid should always be in place.
The water should be cycled and properly filtered. A weekly 10% water change can further improve water quality.
Food
Red Claw Crabs are omnivores that readily accept a variety of foods, including shrimp pellets, fish flakes, brine shrimp, bloodworms, blanched vegetables, and nearly anything else they can get their claws on due to their opportunistic behavior.References:
