Feeding Omnivorous. Diet includes fish, aquatic inverts and some green matter.
Furniture Sand substrate with logs and stones to provide hiding places.
Compatibility Sociable with anything they can not swallow.
Breeding Not accomplished in the aquarium. Suggest overwintering in a pond. Move the fish indoors to a large tank in the spring. The male will dig a nest and the fish should spawn as the water is gently warmed over a few days to 21C. Since they are sexually mature at six inches, this would be a good candidate for the expert looking to try something new.
Breeding Reports There is no breeding report.
