The Red Sea Picasso triggerfish ( Rhinecanthus assasi ) or Arabian Picasso triggerfish lives in the Red Sea , and in the far northwestern Indian Ocean in the Gulf of Aden , the Gulf of Oman and the Persian Gulf . It is the only species of the genus Rhinecanthus in the Red Sea and is distinctive there.
features
The Red Sea Picasso triggerfish becomes 30 centimeters long. In terms of color, it is similar to the Indo-Pacific pelvic Picasso triggerfish ( Rhinecanthus verrucosus ), but lacks its characteristic dark spot on the belly. In the Red Sea Picasso triggerfish, the anal region is yellow or reddish brown from the otherwise whitish belly. In front of the tail stalk there is a white field, which is marked with three black vertical stripes.
Way of life
It lives in the shallow water of reef terraces and fringing reefs to a depth of ten meters. Young fish stay between knotty hard corals ( Acropora , Pocillopora and Stylophora ) or hide in snail shells. Red Sea Picasso triggerfish feed primarily on bottom-dwelling invertebrates.
