Also known as the lyretail coralfish, the lyretail anthias or the scalefin anthia, but may be simply known as the goldfish. The sea goldie is a common sight to scuba divers in the Indian Ocean, and is a typical representative of the subfamily of Anthiinae (Anthias).
Range
The sea goldie is found in the western Indian Ocean including the Red Sea, and in the Pacific Ocean as far east as Japan and southeast Australia. It is absent from the Persian Gulf and Oman.
Description
This species shows marked sexual dimorphism;
Female: Length up to 7cm, orange/gold colour with violet streak below the eye
Male: Length up to 15cm, fuschia colour with elongated 3rd ray of the dorsal fin, a red patch on the pectoral fin and elongated margins of the tail.
The midas blenny, Ecsenius midas, goes through a phase of yellow colouration and is a social mimic of the sea goldie.
Diet
The sea goldie feeds primarily on zooplankton.
Biology
Like other anthias the sea goldie is a protogynous hermaphrodite; a male retains a harem of 5-10 females, but when the male dies one of the females will undergo sex reversal and take the place of the missing male.
Reproduction occurs at sunset, betwen December and February (in the red sea).
Habitat
Around coral outcrops in clear lagoons, patch reefs and steep slopes to a depth of 35m, often to be found in the company of Chromis diademata . They are often found in very large swarms above the reef.
