Notes: The Pearlscale Butterflyfish is a very pretty fish. It's moderate in size at about 5 1/2 inches in length but has an eye catching color pattern. Its body has black edged pearly scales that give it a cross-hatched or netted pattern overall. It is accented with a black eyebar to the front and a bright orange red on the rear. Thus it is known by several other descriptive common names including Yellowtail Butterflyfish, Crosshatch Butterflyfish, Netted Butterflyfish, Orange Butterflyfish, and Crowned Pearlscale Butterflyfish.
This butterflyfish is moderately hardy and makes a good choice for an intermediate aquarist with some experience. It needs a good sized aquarium that is well established. A 55 gallon tank is the minimum size for a single fish, and a bigger tank will be needed if you want to keep more than one. Decorate the tank with rocks and/or corals with many hiding places along with plenty of swimming space. It swims freely and usually spends a good deal of its time in the open water, moving in and out of crevices.
