Tank setup: Use lots of plants. They will leave the plants alone. Add piles of rock and wood to provide hiding places.
Waterconditions: Temperature 15-25ºC (21-23ºC is ideal). Acidity can vary between pH6.5 to pH7.8 and water hardness ranges from 12-18dGH.
Feeding: Will eat nearly everything. Detritus, dead fish, small snails, dead plants and special crayfish food. They also like boiled vegetables and deep frozen food like larvae. Clean dried leaves from oak, wallnut and birch trees can be put in the tank as well.
Breeding: The young seem to be sensitive for changes in the quality of water.
Tank mates: Small friendly animals. Small fish and shrimp. Very small snails will be eaten. When there is a lack of food they will chase other animals. Do not put fanshrimp in the tank.
