Joculator Angelfish description

The Joculator Angelfish are native to Eastern Indian Ocean, spanning through the Christmas and Cocos-Keeling islands.

They have a striking resemblance to the Bicolor Angelfish, but are void of the vertical blue bar above the eyes of the Bicolor Angelfish. The Joculator Angelfish has a rather blue ring around its eyes with the same blue coloration that traces a thin outline that runs through edges of the dorsal and anal fins.

Setting up the best tank for the Joculator angelfish requires an established marine tank having a minimum of 70 gallon capacity with an abundant amount of live rocks that facilitates algae growth upon which they would graze and enough swimming space for their active swimming.

The Joculator Angelfish can be kept in a reef tank, but caution should be taken as these species will often nip the corals and clam mantles in a continuous search for food.

The Joculator Angelfish can be aggressive towards other Angelfish relatives and hostile to similar looking Angelfish species including the Bicolor Angelfish or even the Rock Beauty Angelfish. This demands they should be housed singly in the tank.

Joculator Angelfish feeding

As omnivores, the best food for Joculator Angelfish should be based on a variety of meaty and vegetable matters including fresh and frozen brine and mysis shrimp, spirulina, algae matters and other prepared Angelfish food.

The Joculator Angelfish should be fed 2-3 times a day with as much as they can finish in a few minutes, this will discourage them from nipping at the corals and clam mantles in search of food.
