Size / Weight / Age
Inhabits waters of low to moderate velocity, between 0 and 300 m elevation. Lives on creeks of more than 0.5 m deep, in ditches and near shorelines of large rivers. Generally swims in small groups at a depth of 20 cm. Insectivorous, the young eat mainly aquatic insects and the adults feed specifically on terrestrial insects (Ref. 36880). Found in a rapidly flowing rainforest stream (Ref. 26130).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Gestation lasts for about 24 days. Produces 10 to 30, rarely more, young. Reaches sexual maturity in about 5 or 6 months.
