The Sea Goldie (Pseudanthias squamipinnis), also known as the Lyretail Anthias, Lyretail Coralfish, and Scalefin Anthias, is better known as the Goldfish. 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. They live around coral outcrops in clear lagoons, patch reefs and steep slopes to a depth of 120 feet. They are found in very large swarms above the reef.
Males grow to a size of about 6 inches while females are only half that on average. Males are orange to gold in color with a violet streak below the eye. Females are a fuchsia color with an elongated third ray of the dorsal fin, a red patch on the pectoral fin, and elongated margins of the tail.
The male sea goldie 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, between December and February (in the red sea).
The sea goldie is a common sight to scuba divers in the Indian Ocean. The sea goldie feeds primarily on zooplankton.
