Biology     Glossary (e.g. epibenthic)

Adults occur in warm springs, canals and ditches with typically slow-moving water, silt bottoms and weedy banks (Refs. 5723; 44091, 44894). Also inhabit creeks and swamps (Ref. 44894). Feed on worms, crustaceans, insects and plant matter (Refs. 7020; 44091). Used for genetic research (Ref. 4537). Several color varieties are popular aquarium fishes, where they attain sexual maturity after 3-4 months and reproduce easily (Ref. 1672). Aquarium keeping: minimum aquarium size 60 cm (Ref. 51539).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

After 24 to 30 days gestation, 20 to 80 young are born (Ref 7020).
