Etymology: Mimagoniates: Greek, mimos = mime + Greek, gonio = angle (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 18°C - 23°C (Ref. 2059)
South America: usually in clear coastal streams from southern Bahia to northern Rio Grande do Sul, Brazil. Also found in some areas of the high Iguaçu River (Ref. 84543).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 3 - 3 cm
Max length : 6.1 cm SL male/unsexed; (Ref. 38597)
Inhabit small to moderate-sized streams or rivers (Ref. 30267). Aquarium specimens reach 9.0 cm TL (Ref. 30267). Mature females keep live sperm cells in their ovary through insemination which occurs during the dry season (Ref. 84543). Spawning period coincides with the rainy season to ensure increased survival of offsprings (Ref. 84543).
