Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 16.5 cm SL macho / no sexado; (Ref. 36377); 20.0 cm TL (female)
Espinas dorsales (total): 18 - 19; Radios blandos dorsales (total): 9-11; Espinas anales 7-8; Radios blandos anales: 7 - 9. This species can be distinguished by the dark line running through the middle of the body and the large black blotch positioned midlength; head profile extremely curved with the mouth on the lower part of the head; in males, the scales have dark edges producing a reticulated pattern, their fins with many dark spots, and a red edge to the dorsal fin; both males with iridescent, greenish-blue head and with gold to copper-colored bodies (Ref. 44091).
Inhabit lakes and rivers with slow to moderate currents, between 5 to 200 m elevation (Ref. 36880). Juveniles feed on aquatic insects, while adults feed on bottom detritus, seeds and leaves. Also naturally feed on snails and other mollusks, but will accept a variety of food in captivity (Ref. 44091). Maximum length 25 cm TL (Ref. 2060).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Deposits eggs in sand depressions. Produces about 200-400 non adhesive eggs with females practicing communal care during the post spawning period (an unusual behavior referred to as "creching", Ref. 44091). A group of 3 or 4 females stand guard over their combined spawns, encircling the expanded group and do not allow any intruders or predators into the rearing arena.
