Centropyge joculator

Centropyge joculator, commonly known as the Coco's pygmy angelfish, is a small and rare dwarf angelfish. They've the typical Centropyge body shape, with the head and front part of the body yellow to orangish-yellow. The back is very dark blue to black. The caudal fin is yellow and around the eyes, dorsal and anal fin run electric blue lines. Juveniles have a black spot with blue outline in the rear end of the dorsal fin.

Like all other angelfish it's hermphroditic and the most dominant fish will turn into a male when there is no other male around. These fish are quite shy (in nature and in an aquarium) so try not to combine them with dominant, large or very active fish and make sure ample hiding spots are available. Because C. joculator is a rare species, less is known compared to most other angelfishes. Most of them do seem to show mainly interest in algae and don’t seem to do large damage to corals. But they might pick on certain corals more than the coral likes. Keeping them well fed seems to reduce the risk, so make sure to feed them a proper varied diet of algae and meaty foods to make them really happy!
