Emperor Angelfish

Emperor Angelfish

The Emperor Angelfish, also called the Imperator Angelfish, the adult form has a fearless, blue body covered with bright yellow horizontal stripes crowning in a yellow to orange caudal fin. Whereas, the juvenile form is black with circular blue and white stripes beginning from the tail.

The Emperor Angelfish requires a 600 litre or larger tank with live rock for hiding and grazing on. They also require a vast amount of rock-work and deep tunnels and caves to hide in and feel safe. This angel may will nip at clam mantles and both soft and stony corals, however hobbyists have known them to be safe with small-polyped stony corals.

It is said that the Emperor Angelfish usually becomes the 'king' of the tank once added and will behave dominantly towards other fish. The transformation of the angelfish will vary in coloration and pattern as it adapts from juvenile to the adult.

The Emperor Angelfish should be fed a diet of mysis or frozen shrimp, marine algae, spirulina, and other meaty items.

  1. I lost the beautiful Red Sea Emperor Angelfish a few months ago. I’d had her for almost 20 years. I purchased another healthy Emperor from Dr. Foster & Smith recently. They are a very hardy fish as far as you provide with liverocks with a few caves, high water quality, and a variety of foods, such as krills, OSI flakes, Hikari Seaweed Extreme and Marine A pellets. Those healthy foods help an angel building a strong immune system as well as keeping a beautiful color.

  2. Absolutely beautiful showcase fish as juvenile or adult. Careful adding to tanks with aggressive fish as delicate in regards to “ich” breakouts. Good eaters & best added as juveniles.

  3. This has got the be the nicest angel you can get. I have had mine for 4 years and it is about 9″, it is the boss of the tank and any new fish I add have to hide from him for a while before they can settle in. He eats everything, and you can even hear him make grunting noises in the tank which is quite cool. Best fish I have!
