It also requires extensive rockwork and deep caves to feel secure. The adult Emperor Angelfish may found nipping at stony and soft corals, clam mantles, but doesn?t disturb other small polyped stony corals. It should be fed a diet of Spirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items. The adult Emperor Angelfish thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4. It is slow to accept captivity and very shy in nature. The adult Emperor Angelfish is susceptible to a variety of parasites and proper quarantine procedures are then recommended. It is not considered reef safe though some specimens have been reported to live peacefully without harassing small-polyped stony corals.

If you understand they cannot be kept together, but would like to purchase two or more in the same order(separate tanks, group order, etc.) you will need to write in the Special Instructions area at the end of the shopping cart that you understand they cannot be kept together.
