Rabbitfish - Siganidae
RABBITFISH - SIGANIDAE Rabbitfish can be seen on every part of a coral reef. Around twenty-eight species live in the Indo-Pacific region. The two species Siganus rivulatus and S. luridus in the past managed to travel through the Suez canal to the Mediterranean Sea. Rabbitfish are voracious and graze on algae, seagrass, tunicates and sponges. Only some of the family are brightly colored, but as with other fish, do their colors become greyish when resting or sleeping. This color change probably happens because they sleep unprotected, offering them a bit camouflage against night hunters. Mating happens around sunset or early mornings during spring time, but depends on the position of the moon. Spawning happens during low tide. Length: 30 cm. Distribution: from India to S.W- Japan, E- Indonesia and N- Australia. White body with yellow back and tail fin, light blue spots and small stripes on head and back. Two brown bands on head and above pectoral fin. Solitary or in small groups, among coral-rich coastal reefs with many algae growth. From -2 to -25 m. Length: 24 cm.
