The crown squirrelfish (Sargocentron diadema) is an active demersal fish, also known as the crowned squirrelfish. It has an oblong body with a slightly elongated snout and large eyes. Its colour is bright red with horizontal white stripes running from the gills to the tail. There are two vertical white lines on the gill cover and an oblique line on the head below the eye. The pelvic, tail, anal, and the second dorsal fin are colourless with red rays at the ends. Its first dorsal fin is bright red.
