The basics

The Blue Angelfish has an overall aqua hue with a yellow tinge to it. The fish's pectoral, dorsal, and caudal fins have yellow tips. The dorsal fins are long and trail into long filaments. There is a striking difference between the juvenile and adult Blue Angelfish--the juvenile fish, unlike the adult, has an overall yellowish brown body and has blue stripes running vertically. As the fish matures, it changes in color till it matches the adult variety. The fish has a compressed body that is discus-shaped, with a dark smudge on its forehead.

14-15 inches

The Blue Angelfish is an aggressive fish and should ideally be housed in an Angelfish-only tank. These fish are even aggressive towards other species of Angelfish. Keeping this fish in a reef tank setup is avoided since it is likely to nip at invertebrates. These fish are hermaphroditic in nature.

The Blue Angelfish requires a tank size of at least 150 gallons to thrive. Ideally, the tank should have enough hiding places so that this fish will feel secure within its habitat. An ideal tank setup would include some corals and plants. However, these fish do nip at stony corals.
