Pygmy Yellowtail Angelfish
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 55 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 is best suited for experienced aquarists with a well-established marine environment.

This fish is small and colorful, adding a nice touch to my tank. I had to be careful with coral placement since it tends to nip at soft invertebrates. Works well with a large tank and plenty of live rock.
Rebecca Pullman –
It’s a beautiful fish with a striking blue body and white tail. I noticed it became aggressive toward a smaller angelfish, so I separated them. Good for experienced saltwater keepers.

The Pygmy Yellowtail Angelfish has been thriving in my 60-gallon tank. I provide plenty of hiding spots and live rock. It’s active and looks great, though I avoid keeping it with delicate corals.
