Habitat and biology
Chaetodontoplus caeruleopunctatus is found at depths between 14 and 40 m. It prefers rock areas with a rich growth of sponges and algae. Its diet is composed of sponges and tunicates. Like all other angelfish it is a protogynous hermaphrodite, with all individuals being female initially and the dominant ones changing to males.

Systematics
Chaetodontoplus caeruleopunctatus was first formally described in 1976 by the Japanese ichthyologists Fujio Yasuda and Yoshiaki Tominaga with the type locality given as the Philippines. The position of this species is indeterminate and its closest relatives have not yet been resolved. It was proposed that it was a hybrid but the consistency of appearance of specimens collected and their numbers strongly suggest it is a valid species.

Utlisation
Chaetodontoplus caeruleopunctatus despite its apparent rarity in the wild is quite frequently found in the aquarium trade and has been bred in captivity.
