Descrição breve
Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 9 - 10; Raios anais moles: 13 - 14; Vértebras: 30. Distinguished from all congeners by the following unique color patterns: a broad subbasal red stripe on the dorsal fin in males; ventral portion of the head with a black reticulate pattern in females; caudal fin orange on the dorsal and ventral portions, yellow on the middle in females (Ref. 75134).
Body shape (shape guide): elongated.
Inhabits ponds with clear water, about 1.5 m deep, connected to shallow creeks of about 0.05 m deep (Ref. 75134). Adults stay close to the surface of the ponds, near emerging aquatic plants while a few juveniles occur in shallow creek (Ref. 75134).
