The Joculator Angelfish, (Centropyge joculator), also known as the Yellowhead Angelfish is a beautiful, not so often seen dwarf marine angelfish that is found only in the Christmas Islands and Cocos-Keeling Islands in the Eastern Indian Ocean. This brightly colored angelfish resembles the Bicolor Angelfish (Centropyge bicolor) but lacks the distinguishing vertical blue bar above the eye. In contrast, the Joculator Angelfish sports a blue ring around its eyes and the same electric blue coloration traces a thin outline along the edges of its dorsal and anal fins.
The Joculator Angelfish is a hardy angelfish that can grow to 3” or more in size. The ideal setup for the Joculator Angelfish is an established marine aquarium of at least 70 gallons aquascaped with a generous amount of live rock and plenty of open spaces to swim.
The Joculator Angelfish should be kept with corals and clams with caution as it may nip at them in search of food. In addition, the Joculator Angelfish is intolerant of conspecifics, so avoid housing more than one Joculator Angel in an aquarium or with other fish that resemble it such as a Bicolor Angelfish or even a Rock Beauty Angelfish.
The Joculator Angelfish should be feed 2 to 3 times per day to help discourage it from nipping at corals or mantels of clams. Feed enriched frozen brine shrimp and mysis shrimp along with spirulina and a quality prepared marine angelfish diet.
