Issue
The most recent distributional records were published by Weitzman & Weitzman (1982: Fig. 229). Most recent systematic description by Weitzman (1966). Commonly exported as an aquarium fish since 1910, Stansch (1914). The courtship and other behavior was studied in detail by Caplan & Dunham (1978) and Kuenzer (1982). Probably introduced into rio Jaquraipe, east of Salvador, Bahia Brazil, Géry (1977) and definitely introduced into baía de Guanabara, Rio de Janeiro, Bizerril & Lima (2001). This species is commonly exported as an aquarium fish from Peru and Guyana.

Biologia     Glossário (p.ex. epibenthic)

Inhabits small rivers with little current and in swamps where they are very common. Forms groups where the males dominate to defend their territory. Is highly appreciated by aquarists (Ref. 12225). Feeds on worms, crustaceans and insects (Ref. 7020). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).

Ciclo de vida ou comportamento de acasalamento Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

At spawning time in captivity, male and female swim alongside one another. Several batches of 1 to 5 eggs are laid among the fine-leaved plants, with a total of up to 200 eggs in some cases; eggs hatch in 30 to 40 hours and fry are free-swimming about six days after (Ref. 7020). Between 24°-27°C, eggs hatch in 24 hours (Ref. 205).
