Diagnosis: 14-18 gill rakers on first gill arch; no large spots on flanks (Ref. 81260). 4-6 bands or 2 rows of dark blotches and short horizontal lines usually visible when stressed (Ref. 50577, 81260). Relatively robust (body depth 26.7-38.2%, mean 34.4% SL); lachrymal depth less than 21% HL (Ref. 81260). No iridescence on cheek, operculum and flanks (Ref. 50577).
Body shape (shape guide): fusiform / normal.
Prefers smaller rivers and creeks; normally found near the banks where plenty of hiding spots are available; diet consists primarily of small particles, preferably plant matter, although shrimp eggs and insect larvae are also taken (Ref. 52307). Monogamous (Ref. 52307), pair-bonding, ovophilic, biparental mouthbrooding species (Ref. 52307, 81260).

In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).
