Description

Also known as Anthias, Anthias Bicolor, Basslet, Fairy Bass, Sea Perch, Yellowback Basslet, Yellow-backed Basslet.

Found singly or in schools, in current prone areas, near to crevices or ledges, above coral outcrops, of lagoon patch reefs and outer reef slopes.
They feed on zooplankton.
Length - 13cm
Depth - 5-68m
Widespread Indo-Pacific

Anthias are often found in large schools, often in their hundreds or thousands, feeding high above the reef on zooplankton.
They start their life off as females, and when there is an opening for a male, will change to head up their harem of females.
Males are much more colourful, and often have filamentous streamers which they use for their mating dance, and to deter other males. Ref: https://www.fishbase.se/summary/Pseudanthias-bicolor.html
