Maturity: Lm ?  range ? - ? cm
Max length : 8.6 cm TL male/unsexed; (Ref. 5723); common length : 4.4 cm TL male/unsexed; (Ref. 12193); max. reported age: 3.00 years (Ref. 12193)
Inhabits sandy runs and pools of creeks and small to medium rivers. Occurs usually in clear water. Often found near vegetation in the north part of range (Ref. 5723, 10294). Feeds on filamentous algae and detritus, in addition to the expected small invertebrates (Ref. 10294).
