Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय सौफट रेज़ (सम्पूर्ण): 10-12; ऐनल सौफट रेज़: 8 - 9; जानवरों की रीड़ का जोड़: 32 - 33. Distinguished from other species of genus Characidium by the bright yellow fin coloration, and by the absence of conspicuous dark bars along the sides of body in
individuals larger than 3.5 cm SL (vs. dark bars or marks present on the sides of the body in specimens of all sizes in the remaining species of Characidium) (Ref. 76854).
Found mostly in riffles, rocky bed with pebbles and sand deposits (Ref. 76854).
