More Info


Distribution

Distribution is restricted to south-eastern Queensland in coastal streams between Bundaberg and Brisbane, and also on Fraser Island, QLD. Tropical species inhabiting slow-flowing, tannin-stained freshwater creeks and coastal dune lakes with sandy or muddy bottoms. Often found amongst aquatic vegetation along grassy banks.

Features

Dorsal fin IV-VI1; 6-9; Anal fin 10-13; Pectoral fin 9-12; Pelvic fin 5; Caudal fin 13-14; Gill rakers 10-13; Vertebrae 28-31

Body relatively elongate, laterally compressed; greatest body depth 19.2-29.4% SL; mouth small with a protractile maxillary; jaw teeth conical to villiform, with or without one or more rows extending outside of mouth; vomer and palatines toothless; eye relatively large; some small pores on head but absent on mandibular.

Scales relatively large, cycloid with well-developed radii; cheek scales 3-4; vertical scale rows 26-29; horizontal scale rows 5-6; predorsal scales 8-12.

Two separate dorsal fins; first dorsal fin originating before tip of pectoral about midway along body; second dorsal fin originates behind anal fin origin; anal fin originating under end or just behind first dorsal and in front of second dorsal origin; dorsal and anal fins lack rigid spines; pectoral fins short, pointed and set in a horizontal plane; caudal fin forked with rounded tips; mature males with elongate anterior dorsal, anal and ventral fin rays.

Size

To 3.5 cm SL.

Colour

Although males and females differ in colouration, both have a blue eye and fine grainy melanophores on the head. Males are generally honey or bronze coloured; first dorsal fin mainly black with white anterior border; anal and second dorsal fins honey coloured with black submarginal band and white border. Females are plain amber colour with clear fins. Juveniles are greyish.

Feeding

Feed mainly on micro-crustaceans and insect larvae.

Biology

Breed opportunistically throughout the year. Males display to females by intensifying their colours and erecting their ornate fins. Breeding episodes last several days with females depositing 4-10 adhesive eggs per day amongst aquatic vegetation. Larvae hatch in 2-3 weeks.

Fisheries

A popular aquarium species.

Conservation

IUCN Red List: Endangered

EPBC Act: Vulnerable

Remarks

Males differ from females in having brighter colouration and more elongated dorsal fins. The rapid decline in numbers of this species may be linked to the removal of suitable habitat for housing developments.

Similar Species

Pseudomugil mellis is similar to P. signifier but differs in having smaller scales on the nape, smaller cephalic sensory pores, and the dorsal, anal and caudal fins of males have a black band edged with white.

Etymology

Generic name Pseudomugil is from the Greek pseudes meaning false, and the Latin mugil meaning a fish, most likely a Mullet. The specific name is from the Latin mellis meaning honey, in reference to the body colour.
