Biology     Glossary (e.g. epibenthic)

Occurs in shallow, cool, clear, quiet, heavily shaded forest streams, usually with a silty substrate and often in areas with a large amount of leaf debris in the water. Feeds on terrestrial insects (Diptera and Coleoptera, see Ref. 6469) and detritus. Males slimmer and brightly colored than females.

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

A prolific breeder. The courtship ritual is frenetic; several batches of about 20 eggs are spawned among submerged marginal vegetation during the course of about 30 minutes. The eggs sink, and hatch in about 36 hours. The free-swimming fry are very delicate and sensitive to water conditions.
