Descrição breve
Chaves de identificação | Morfologia | Morfometria
Favors the shallow mud bottom waters near fringing vegetation such as papyrus and Vossia (Ref. 9606). Feeds on aquatic insects, mainly chironomid larvae (Ref. 12526), on Caridina and caenid larvae (Ref. 9606), but also on algae and plankton (Ref. 36900). A male to female ratio of 1:10.5 has been noted for this species; it breeds continuously throughout the year with obvious peaks during the rains (Ref. 10608). Anadromous (Ref. 10608). Migrates up the rivers to spawn in temporary pools and streams (Ref. 4903, 10608). Oviparous (Ref. 205).
