📖 Overview

Prefers deeper portions of slow-flowing creeks and rivers, as well as billabongs. Inhabits clear and turbid waters, over muddy to rocky substrates, often where algae is abundant. Adults occur in shoals around snags. Juveniles are mostly found in riffle habitat. Sympatric with Syncomistes holsworthi, S. kimberleyensis, S. rastellus and S. trigonicus. Feeds mainly on filamentous algae along with some detritus and invertebrates. Attains sexual maturity at 120-140 mm and spawns in wet season. Eggs are large about 3 mm and non-adhesive .
