Passer Angelfish (Holacanthus passer) – King Angelfish
The Passer angelfish, also known as the King Angelfish, is a striking large angelfish species. Juveniles are orange with blue bands, transitioning into dark blue with a wide white vertical band as they mature.
These fish are hardy and well-suited for fish-only tanks housing other large, semi-aggressive species. Juveniles should be introduced using an acclimation box to reduce the risk of aggression.
Feeding should occur three or more times daily. A diet of small pellets is recommended, supplemented with omnivore foods and angelfish-specific frozen foods, including sponge-based options.

The Passer angelfish is a stunning addition to my tank. The color change from orange to dark blue is impressive. I feed them three times a day with a mix of pellets and frozen food. They’re active and peaceful once acclimated, though I used an acclimation box for the juveniles to avoid stress.

Beautiful fish with a unique appearance. They grow steadily and seem to enjoy the frozen food I offer. I made sure to introduce the young ones slowly using an acclimation box. They haven’t shown aggression toward other large fish in the tank.

Great hardy fish for a larger tank. The white band on the adult is very noticeable. I feed them small pellets and frozen angelfish food with sponge. They’re easy to care for and stay active in the tank.
