Short description Morfología | Morfometría

Predorsal midline with a continuous series of scales covering more than three quarters of the distance between the posterior tip of supraoccipital spine and dorsal-fin origin and the caudal-peduncle spot restricted to the midlateral axis of the body, not extending on to the dorsal and ventral margins of bases of caudal-fin rays (Ref. 119406).

Recorded in streams and ponds between 1 and 60 m elevation. Schools are found in waters ranging from stagnant to swift current at temperatures of 24 to 28°C. Feeds on seeds, terrestrial and aquatic insects (Ref. 36880).
