They are dark brown along the back and paler on the sides, with fuzzy dark lines running along scale rows.<ref name="fishes" />  Juveniles have a white or cream patch running along the back and top of the head, with brown sides and a white belly.<ref name="fishes" />

Females spawn in the [[benthic zone]] from October to February.  Males guard nests of up to 70,000 eggs until larvae hatch, usually after 5–7 days.

They are usually found in quiet or slow-flowing water in freshwater rivers, creeks, and [[billabong]]s throughout northern Australia.<ref name="fishes" />
