Minimum Tank Size: 55 gallons

The Pygmy Yellowtail Angelfish, also known as the Royal Blue Pygmy Angelfish, is one of the smallest members of the Centropyge genus and typically grows up to two inches in length. Its body and face are predominantly blue, while the caudal fin is white. Other common names for this fish include Damsel Angelfish, Whitetail Pygmy Angelfish, Pygmy Yellowfin, and Pygmy Yellowtail Angelfish.

To ensure the optimal environment for this fish, it requires a tank of at least 55 gallons in size with plenty of hiding places and ample amounts of live rock for grazing on microalgae. However, it is not suitable for reef tanks as it has a tendency to nip at stony and soft corals as well as clam mantles. Additionally, the Pygmy Yellowtail Angelfish is territorial and may attack and kill other Dwarf Angels and harass docile fish.

Keeping one male and several females together is possible, and breeding in an aquarium is feasible. However, there are no discernable differences in coloration between males and females.

The Pygmy Yellowtail Angelfish's diet should include Spirulina, marine algae, high-quality angelfish preparations, mysis shrimp, and other meaty items, and should be fed multiple times per day.
