Short description
Claves de identificación | Morfología | Morfometría
Has 1/2 4 scale rows between the dorsal-fin origin and the lateral line; a conspicuous, narrow, black longitudinal stripe along the sides, widening into a diamond-shaped blotch on the caudal peduncle (Ref. 27732). Scale margins outlined by reticulated dark pattern; black tips on caudal lobes present or absent; lateral line complete (Ref. 12693).
Associated with clear, usually shallow and moderately flowing streams (Ref. 27732). Occur near the surface in small to medium-sized streams in upland areas. Individuals from high-gradient upland streams have a much darker stripe and often black tips on the caudal fin lobes. Feed probably on exogenous insects (Ref. 12693). Spawning sites are found in rivers and ponds (Ref. 33813). Mature adults probably breed during the rainy season. Not seen in the markets, but occasionally imported in the aquarium trade (Ref. 12693).
