Épines dorsales (Total) : 6 - 7; Rayons mous dorsaux (Total) : 8 - 9; Épines anales: 3; Rayons mous anaux: 7 - 9; Vertèbres: 25 - 26. Head deep and laterally compressed; pores on head and lower jaw; snout tapered. Insertion of the pelvic fin in line with the third dorsal spine and well behind pectoral fin base. Pelvic girdle length at least twice its width. Caudal fin rounded. Cleithrum's posterior margin and opercular spines without serrations; post temporal serrated.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits a broad (30-40 meters wide), clear, flowing stream with a rocky bottom. Temperature ranges between 15° and 25°C and pH from 5.0 to 6.0. During the day it shelters in the cover of undercut banks, boulders, log snags and submerged root masses, darting into crevices if threatened. Nocturnally active, feeding on insects and their larvae, crustaceans, fishes and plant matter. Sexual maturity is reached at a length of about five centimeters. One of the most recently discovered Australian freshwater fish species (Ref. 44894).
