Comments: Recorded from near Paramaribo (Ref. 26144). Research on ecology and breeding in captivity being done by University of Suriname. N.V. Cammewijne Shrimp Fish Culture Co. (COMFISH) collect eggs from wild and grow-out in 20 ponds of 0.5 ha each (Ref. 26042). This species is in danger of local extinction (Ref. 26554). Overfishing, human-induced habitat modifications and the introduction of the exotic Oreochromis mossambicus pose a serious threat to its survival (Ref. 26554). Also Ref. 37395.

Max length : 26.3 cm TL hane/ej könsbestämd; (Ref. 104645); rapporterad maxålder: 4 år (Ref. 51639)

Obligate air-breathing (Ref. 126274); Inhabits swamps (Ref. 11225). During the rainy season, adults consume a great quantity of chironomids associated with detritus. During the dry season, they feed mostly on terrestrial insects, micro-crustaceans, aquatic Diptera, and detritus. Absorbs a great quantity of anaerobic bacteria from the substrate (Ref. 27188). First reproduction occurs after one year (Ref. 35381). Used to be cultured commercially in Guyana (Ref. 7306). Cultured in Trinidad on a semi-commercial scale (Ref. 11225).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Reproduction begins with the rainy season (December-January). The male, at times helped by the female, builds a nest made of a cluster of mucus bubbles and vegetal matter. Responding to a nuptial parade, the female lays down her eggs (5,000 to 20,000, measuring1.8 mm in diameter) which are fertilized by sprinkling sperm previously collected in her mouth. The male guards the eggs during incubation and becomes very aggressive (Ref. 35381).
