Other Names: Fire-tailed Gudgeon, Gale's Carp-gudgeon

Summary:
A small greyish to bronze gudgeon with dark scale margins, especially along the mid-side (may appear as a faint mid-lateral stripe), a silvery belly that appears orange to pink in gravid females, and often a black bar above the pectoral fin base. Adult males have elongated rays in the rear of the second dorsal and anal fins, with the fin tips extending along the length of the caudal peduncle, 
Breeding males become blackish with a broad reddish-orange margin on the dorsal and anal fins, and a dusky reddish-orange caudal fin. Females have transparent fins and black pigment on and around the genital papilla.

More Info


Distribution

Coastal drainages of eastern Australia, from Water Park Creek, central Queensland, to the Georges River,  central New South Wales, including Fraser, Bribbie, Moreton and North Stradbroke islands (and possibly south to Yadboro, west of Ulladulla, New South Wales). This species has also been translocated elsewhere in the Murray-Darling Basin in Queensland and New South Wales. Inhabits coastal freshwater streams, large rivers, floodplains, coastal wetlands, dune lake systems, dams and weirs, often around aquatic vegetation.

Features

Dorsal fin VI-VIII; I,10-12; Anal fin I,11-13; Caudal fin (segmented rays) 15; Pectoral fin 14-15; Pelvic fin I,5; Gill rakers 9-12; Longitudinal series 31-33; Vertebrae 29-30.
Head and body distinctly compressed, body moderately slender, tapering toward tail. Males developing slight hump on top of head behind eyes. Mouth small, oblique, reaching to below anterior margin of eye; teeth small in several rows in both jaws. Tongue tip truncate. Gill opening moderately broad, extending forward to below posterior end of preoperculum. Pectoral base narrow, with rays developed ventrally; a free fold of skin extending to upper attachment of opercular membrane above uppermost ray. Head pores absent.
Body scales ctenoid, lateral line absent; top of head scaled forward to above posterior half of eye, predorsal scales 8-12; cheeks and gill covers with small cycloid scales, none on snout.
Two dorsal fins; first dorsal with rectangular margin in males, rounded in females; second dorsal higher than first; anterior rays of second dorsal and anal fins elevated, posterior rays elongated in males. Caudal fin truncate to slightly rounded. Pelvic fins separate.

Size

Males to around 5.5 cm SL; females to 4 cm.

Colour

Colour varies according to habitat, time of year and age of the individual fish. The colouration of the species varies with age, habitat and season. Body generally grey to bronze or almost black, with a black bar on the side above the pectoral fin base, covering the upper two thirds of base, becoming narrower and paler ventrally; faint stripe from black bar to tail base; scales edge in black; belly paler. Fins clear to dusky; basal two thirds of dorsal and anal fins darer than margins; large fish with dusky bases and reddish orange margins; caudal fin clear to reddish orange.

Feeding

Feeds mostly on insects, larvae and small crustaceans such as cladocerans and ostracods.

Biology

Oviparous, spawning from October to January. Females attach batches of 25-440 eggs beneath substrates such as stones, leaves or shells between late winter and early summer. The male parent guards and fans the eggs until the larvae hatch after up to 7 days.

Similar Species

Hypseleotris galii differs from H. acropinna and  in having dark pigment on and around the genital papilla in females; differs from H. moolooboolaensis generally in having fewer lateral scales (31–33 rather than 33–34 in H. moolooboolaensis).
The species differs from other southeastern Australian species in having adult males with elongated rays in the posterior portions of the dorsal and anal fins, with fin tips extending along the length of the caudal peduncle. In breeding males, the median fins have distal bands of pale orange, and a dusky red caudal fin. 

Etymology

The species is named galii in honour of Ogilby's friend, Mr. Albert Gale, who observed the fish in the Sydney Botanic Gardens, suspected it was a new species, and assisted Ogilby with collection of the fish.
