Amphiprion percula typically reaches a length of 8 cm but can grow up to 11 cm. It is characterized by three distinctive white lines on its bright orange body, with no color differentiation between genders. The first white bar is situated just behind the eye, the middle bar runs down the center of the fish, and the posterior bar is near the caudal fin, featuring an anterior projecting bulge. Black edging outlines each fin with varying thickness. The species has 10 spines in the first dorsal fin.
