背鰭 (合計) : 11 - 14; 臀鰭: 11 - 13; 脊つい: 35 - 38. Can be diagnosed by having the following characters: dorsal fin with iii, 9-11 rays; anal fin with iii, 9-10 rays; dorsal fin in males grayish; anal fin in nuptial males white; absence of black blotch on dorsal fin in juveniles; eggs short ellipsoid, ratio of major axis to minor axis, 1.4-1.7 (Ref. 78070).
Inhabits rivers, creeks, lakes and ponds in plains. Also occurs in mouths of rivers draining into lagoons, in rocky shores of rivers and irrigation creeks, and in floodplain pools. Deposits its eggs into host mussels (Ref. 78070).
