Overview
The Blueline Angelfish, also known as the Bluebanded Angelfish, has been likened to a butterflyfish in body structure. This unique fish is only available on a seasonal basis in the summer months. As a juvenile, this species can be recognized by its dark black body with iridescent blue horizontal stripes, along with a yellow bar that runs vertically behind the eye. The dorsal and anal fins are outlined in white and the caudal fin is bright yellow. As an adult, a yellow to tan body with vibrant blue horizontal stripes identifies this fish.

The Blueline Angelfish is a relatively shy species when first introduced but will adapt quickly to a well-established aquarium. Providing a quietly located aquarium with non-aggressive tank mates and plenty of hiding places is ideal. A minimum of a 180-gallon tank or larger provided with live rock for grazing will also help provide an optimal environment. The Blueline Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. It will also graze on microalgae, filamentous algae, and diatoms.

The diet should consist of mysis or finely shaved frozen shrimp, quality marine pellet food, clams on the half shell, and other meaty items, along with algae and sponge.
