Description

Pseudanthias rubrizonatus males are pinkish to pinkish orange at the anterior end of the body and are frequently bright yellow on the posterior of the body and on the tail, these two areas being separated by a wide red, vertical bar. There is a lilac coloured stripe which runs from below the eye to the lower part of the base of the pectoral fin. The dorsal fin has a lilac margin as do the outer lobes of the caudal fin. The females are reddish-pink, paler ventrally, and each scale has a dark spot in it. The females also have a violet stripe from below the eye to the lower part of the base of the pectoral fin and have red tips to the lobes of the caudal fin. The juveniles show lavender tips to the spines in the dorsal fin.[3] The dorsal fin contains 10 spines and 16 soft rays while the anal fin has 3 spines and 7 soft rays. The maximum total length is 12 centimetres (4.7 in).[2]

Distribution

Pseudanthias rubrizonatus is found in the Indo-Pacific where it occurs from the Andaman Sea east as far as Fiji, north to southern Japan and south to Australia and the Great Barrier Reef.[1] In Australia it occurs as far south as Sydney, New South Wales.[3]

Habitat and biology

Pseuadanthias rubrizonatus is found at depths of 3 to 152 metres (9.8 to 498.7 ft),[1] in aggregations around isolated coral heads and patches of rubble. The juvelines may be found in harbours and over silted coral reefs.[2] It is a protogynous hermaphrodite and when the male dies or disappears the most dominant female changes into a male.[4] They normally feed on zooplankton but are opportunistically piscivorous.[1]

Taxonomy

Pseudanthias rubrizonatus was first formally described in 1983 as Anthias rubrizonatus by John E. Randall with the type locality given as the southwestern side of Savo Island in the Solomon Islands.[5] This species is placed in the subgenus Pseudanthias by some authorities[6] and it is similar in appearance to Pseudanthias connelli of South Africa.[2]

Utilisation

This species appears in the aquarium trade.[4]
