Sides with up to 12 dark bars, more prominent on males and diffused or absent in females. Caudal fin margin yellow or orange, submarginal darkened band in males. Distal half of dorsal fin yellowish or orange; the margin of the fin is black. Anal fin yellow with a black blotch. The gonopodium is shorter (mean 30.4% of SL) than B. olomina (mean 32.9 of SL) (Ref. 36880).
