Red Clawed Crab

Sesarma bidens

Red Clawed Crab is common found on mud flats, sandy beaches and river banks in estuarine areas, particularly around Hong Kong. Red crabs will catch small fish and eat them if they can. Crabs can be kept in groups, providing there is enough space for them to hold territories, otherwise they will fight a lot. Keep one male to about three or four females.

Most fishkeepers and shops keep their Red crabs in normal aquaria with no access to 'land'. However, experts say that they do best when they are given access to 'land', so some form of 'beach' in the tank would be beneficial for their long-term well-being. Provide plenty of cover in the form of bogwood for the crabs to climb on and hide under. Plants can be added - but the crabs may prune them for you. Whatever style of tank you adopt, always ensure that it is well secured. Red crabs can climb out of the aquarium if given the chance, and they may look at cables entering the tank as an escape ladder out of the aquarium.

Red crabs are omnivorous. They will happily accept both meaty foods such as small pieces of lancefish, bloodworms and catfish tablets, as well as vegetable foods such as frozen peas and aquatic plants.
