Also: Florida crayfish
Family: Cambaridae.
Characteristic: Male has two extra short appendages at the rear of the back legs. Female has none. In the aquarium can grow up 5 inch (13 cm).
Tank and water: 20 Gallons (75.7 Liters), Ph 7 -7.5, 65 - 75°F (18.3 - 23.9°C)
Care: They like to burrow and hide in caves. They can live in the aquarium, as long as there are not other bottom dwellers or expensive fish. These creatures are scavengers as well as hunters. They clean up the bottom the tank, but will also grab at a passing fish too. They too can be eaten by fish. A large oscar, for example, would consider it for lunch. When they molt their protective shell they are vulnerable to smaller fish also.
Crayfish are great escape artists and will try to climb out of the tank, so any holes in the hood should be covered.
Feed food which is high in Iodine as this helps it moult. Kelp tablets are one source.
Illness: It can be affected by a leach worm kind called Branchiobdellida. This is not dangerous for the crayfish and can be removed rinsing and scrubbing with a soft toothbrush under tank temperature water.
Compatibility: With any medium size fish.
