Summary:
Males are lavender pink with four diagonal yellow bands on the head and body, those in the middle breaking up into a series of large irregular spots ending in a large spot on the lower caudal-fin lobe, a broad yellow stripe along the middle of the dorsal fin, and broad yellow outer parts on the anal and pelvic fins. They also have filamentous caudal-fin lobes.
Females are mostly lavender pink becoming yellow on the rear of the body, caudal peduncle and most of the caudal fin. The species has a yellow bar across the anal-fin spines, yellow pelvic fins with a pink leading edge, and a yellowish-brown blotch on the front of the dorsal fin.
