The midas blenny, "Ecsenius midas", goes through a phase of yellow colouration and is a social mimic of the sea goldie.
The sea goldie feeds primarily on zooplankton. Like other anthias, the sea goldie is a protogynous hermaphrodite; a male retains a harem of five to 10 females, but when the male dies, one of the females will undergo sex reversal and take the place of the missing male. Spawning occurs at sunset, between December and February.The sea goldie appears in both games of the Endless Ocean franchise.

Habitat
The fish lives around coral outcrops in clear lagoons, patch reefs, and steep slopes to a depth of 35 m, often found in the company of "Chromis diademata". They are often found in very large schools above the reef.References:
