Épines dorsales (Total) : 15 - 16; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 4; Rayons mous anaux: 6 - 7. Diagnosis: mouth large and protrusible; premaxilla reaching upwards to level of occipital region; preopercle denticulate; lateral line absent; 5 scale rows on cheeks; caudal fin rounded (Ref. 57397).
Coloration: highly variable, depending, among other factors, on emotional state of fish; normally, ground colour dark brown; iris red; opercula with a large black blotch bordered posteriorly by a bright red band; under stress, colour turns rapidly into a marbled pattern with alternating light and dark brown cross bars; in young individuals, sides show a series of light cross bars (Ref. 57397).
Occurs in running freshwater (Ref. 6801). Maximum TL recorded was 4.8cm (Ref. 6801).
