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.
