More Info


Distribution

Recorded from fast-flowing coastal streams in northern Queensland - from north of Daintree River to south of Cairns. The species occurs elsewhere in the West-Pacific - Indonesia (Irian Jaya), Papua New Guinea, Solomon Islands, Vanuatu, Fiji and New Caledonia.

Inhabits the lower reaches of fast-flowing clear oxygen-rich streams over rocky bottoms - at the salt-water limit..

Features

Distinguished from other species of Stiphodon in having 10 segmented rays in the second dorsal-fin, and males have filamentous spines in the first dorsal-fin, usually 14 pectoral-fin rays, and the distinctive colour pattern of the male.

Colour

Males and females are sexually dimorphic. Mature males have 9-11 bright orange/red bars along the body, 6-7 dark saddles on the upper surface, a pale belly, and a bright blue upper lip, cheek and opercle. The first dorsal fin is reddish with dark bars along the spines. The second dorsal and anal fins are blackish with a narrow pale bluish to whitish submarginal band. The caudal-fin is reddish with yellow outer rays and often a pale bluish to whitish submarginal band. The pectoral and anal fins are reddish.
Females are pale with a single, dark, midlateral stripe.

Feeding

Omnivore - feeds on algae and small invertebrates and is amphidromous.

Biology

Little is known of the biology and ecology of this species. The species is amphidromous - spawning occurs in freshwater and the larvae are washed downstream to the sea, and migrate back to freshwater. Like other species in the genus, females presumably lay adhesive eggs onto the underside of rocks in freshwater streams. The larvae are presumably carried downstream to the sea, before migrating back to freshwater as very small juveniles (Maeda & Tan 2013). 

Fisheries

Sold in the aquarium industry.

Conservation

IUCN Red List: least Concern

Etymology

The specific name rutilaureus is from the Latin rutilus (red), and aureus (golden) reference to the colour pattern of adult males.

Species Citation

Type locality: Letak Creek, about 25 kilometers southeast of Wewak, New Guinea, Papua New Guinea, elevation 350 m.
