| Bones in OsteoBase |
| Specialized organs | protruding genital papilla (m) |
| Different appearance | always different morphology between mature adults |
| Different colors | different colors during breeding season only |
| Remarks | Females have slightly longer pelvic fins than males relative to body length. Upper caudal lobe of the female was longer than the lower lobe by a greater percentage in the female than in the male (Ref. 40683). The genital papilla of the male is firm, pointed and white-tipped, while that of the female is soft and rounded (Ref. 205). |

Greenish yellow above, shading to white below, with 5 prominent vertical black bars that narrow toward belly (Ref. 26938). A faint sixth bar may be present posteriorly on caudal peduncle; a black spot at upper base of pectoral fin. The adult male becomes dark bluish, the black bars thus less conspicuous on the body (Ref. 13442). |
