The body is oval, the side is flat, the kiss is prominent, and the mouth is small. The small, long mouth has comb like teeth arranged in narrow rows. There are prominent spines in the front of the dorsal fin. The forehead is concave and the nose is short. The appearance of young and adult fish is completely different. They have a large circular black spot at the bottom of their dorsal fin. There are four vertical body lines, but the overall color is brownish yellow rather than white. There is a black band on the head through the eyes, two black wide transverse bands on the body side, and a black band along the dorsal fin, caudal fin and gluteal fin, with white outer edge. Young fish may retain this spot up to 5 cm and then begin to disappear. The ventral fins of all ages are black.
