More Info

Distribution	Known only in Western Australia from the Murchison River to the Gasgoyne River; inhabits small, quiet freshwater pools with moderately turbid water and boulder substratum littered with dead tree branches.
Features	Meristic features: Dorsal fin VI; I, 10; Anal fin I, 11; Caudal fin (segmented rays) 15; Pectoral fin 14-16; Pelvic fin I, 5; Transverse scales 10-13; Vertebrae 26; Gill rakers 2-3 + 1 + 8-9 = 11-13. Head and body distinctly compressed; body relatively deep, depth 4.3-5.0 in SL. Adult males with prominent forehead hump from above upper end of opercular margin to snout. Mouth small, very oblique, reaching to or not quite to middle of eye; both jaws with small teeth in several rows; tongue tip truncate. Gill opening moderately broad, reaching forward to below posterior end of preoperculum. Head pores absent, sometimes with up to 5 preopercular pores and sometimes two pores above each eye. Cheek sensory papillae normally in longitudinal rows, with few vertical rows Body scales large and ctenoid, lateral line absent; longitudinal series 34-43; scales often cycloid on belly and nape; predorsal scales forward to above middle of eye, 16-21; scales in transverse series 10-13; cheek with 4 rows of small embedded cycloid scales’ operculum covered with medium-sized cycloid scales. Two dorsal fins; posterior dorsal and anal rays not prolonged in males. Pelvic fins separate, short, reaching half to two-thirds of distance to anus. Pectoral base narrow, rays developed ventrally; free fold of skin extending to upper attachment of opercular membrane above uppermost ray.
Size	To around 6cm SL.
Colour	Body with 6-9 vertical brown bands, width about equal to eye diameter; bands more pronounced anteriorly and dorsally, often fading on caudal peduncle; snout and head above eye dark brown in adult males; black bar at pectoral base, entirely above pectoral rays. Second dorsal fin with 2-3 rows of small dark spots on basal half of fin, surrounding white to clear spots; distal tip of fin dusky, sometimes whole fin dusky; extreme tip of anal usually white; small dusky spot at base of caudal rays below midside.
Feeding	Feed mainly on aquatic invertebrates.
Biology	Oviparous benthic spawners.
Similar Species	Closely related to H. regalis of the Prince Regent Reserve, West Kimberley. It differs from this species by possessing an additional vertebra (26 versus 25) and smaller scales.
