Aquarium setup: A tank with driftwood and plenty of caves is recommended. A planted tank is not ideal as the species will uproot and eat plants.

Feeding: These crayfishes main diet should be vegetable matter but they will filter feed debris and pellets off the bottom, as well as, eat live plants.They will eat dying or dead fish. Brine shrimp, tubifex worms, and bloodworms will also work.

Breeding: To breed raise the temperature in the tank above 80F to simulate the hot season. Perform water changes and feed the crayfish live foods like mysis, brine, or even beefheart. The female will carry her clutch under her tail or swimmerets until ready to hatch.
