[edit] Sexing

Males are more brightly coloured than females. Females also have a different shaped abdomen, only visible on the underside.

[edit] Tank compatibility

Really best kept in species tanks and can live with other crabs but may fight with other crabs if not enough space to set up territories, but if kept with fish they must not be kept with long-finned fish, bottom dwellers or small fish species. Top dwelling and fast-swimming fish that prefer brackish conditions only.

[edit] Diet

An omnivorous crab which will take most foods including blanched vegetables, flakes and pellets, brine shrimp, bloodworm and fish.

[edit] Feeding regime

Feed once or twice a day.

[edit] Environment Specifics

Must have access to an area above the water line, and prefers brackish conditions, an SG of 1.005 is sufficient. A secure fitting lid is essential as these are excellent escape artists. Red crabs are particularly sensitive to copper, which is an ingredient in many fish-disease treatments and snail-eradication chemicals, avoid at all costs.

[edit] Behaviour

An active crab that climbs well. Red crabs will catch small fish and eat them if they can.

[edit] Identification

Flattened deep red/brown shell with protruding eye stalks and 2 equal-sized bright red claws.
