Description

Also known as Evansi Anthias, Evan's Anthias, Goldback Anthias, Purple Wreckfish, Sea Perch, Two Coloured Coral Perch, Yellowtail Basslet, Yellowtail Fairy Basslet, Yellow-tailed Basslet, Yellow Goldie, Yellowtail Goldie.

Found in large schools, over upper parts of drop-offs and slopes, of outer reef lagoons.
They feed on zooplankton.
Length - 12cm
Depth - 4-40m
Widespread Indian Ocean.

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-evansi
