Morphology | Morphometrics
soft rays: 17 - 20. Distinguished from all other species of the genus by its humpback, convex dorsal profile and concave transition between head and body along dorsal midline, numerous small and irregularly set scales in the longitudinal series, 26-30 gill-rakers in contrast to 12-15 in other species, long and closely set, dark vertical bar through the eye, uniform drab male color pattern, and courting behavior (Ref. 26692).
Occurs in temporary pools. 8 cm max TL (Ref. 3788). Bottom spawner, 3 months incubation. Very difficult to maintain in aquarium (Ref. 27139).
