Ventral body wall gently rounded toward caudal peduncle, more rounded in ripe and gravid females. Caudal fin rounded. Caudal peduncle shorter than deep. Sexual dimorphism well developed, with males usually 10-15% larger in SL than females and with soft dorsal, anal and pelvic fins more elongated. First ray of pelvic fin always longest in males, in females second ray of this fin always longest. In males, tip of pelvic fin can reach or overlap origin of anal fin.
