It occurs at elevation from 0-600 m in lakes, rivers and creeks, and tolerates temperate ranging from 21-34°C (Ref. 95069). Angulo, A., J. Marlene and M.

This species can be further diagnosed from B. guatemalensis by the following combination of characters: 5 or 6 rows of scales between lateral line and pectoral fin base (vs. 7 or 8); 9 to 11 (generally 10) rows of scales between lateral line and dorsal fin base (vs. 10 to 12, generally 11); 5 to 7 (generally 6) rows of scales between lateral line and anal fin base (vs. 7 to 9, generally 8); and a elongated and shallow caudal peduncle, whose length is 1.78 to 2.35 times its depth (vs. a short and deep caudal peduncle, whose length is 1.25 to 1.61 times its depth) (Ref. 95069).
