One of the smallest members of the Centropyge genus, the Pygmy Yellowtail Angelfish rarely grows to over two inches. Also known as the Royal Blue Pygmy Angelfish, Damsel Angelfish, Whitetail Pygmy Angelfish, Pygmy Yellowfin, or Pygmy Yellowtail Angelfish, its body and face are primarily blue and the caudal fin is white.

It requires a 25 gallon or larger tank with numerous hiding places and large amounts of live rock for grazing on microalgae. Not a good reef dweller, the Pygmy Yellowtail Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. It can be very territorial and will often kill other Dwarf Angels, and harass any docile fish.

One male and several females can be kept together. The Pygmy Yellowtail Angelfish can be bred in an aquarium, but has no distinguishing characteristics that differentiate males from females.

The diet should consist of Spirulina, marine algae, high-quality angelfish preparations, mysid shrimp, and other meaty items.
