This species of angelfish is found more frequently than any other in home marine aquaria. It is a very successful species, ranging from East Africa across the Indo-Pacific to Ceylon and into the Pacific Ocean to the Philippines. Unlike many other marine fishes with a wide range, there is surprisingly little variability in colour and form within the species. It is almost impossible to differentiate between a specimen from Kenya and one from the Philippines. However, although little variation is seen among adult fishes, the variation in colour pattern among developing juveniles within this genus is amazing. Below are shown some phases in the development. This phenomenon has created a great deal of confusion in the ranks of amateur taxonomists. Animals of the same species but at different stages of development have been named as a new species, and even attributed to different families.

Once acclimatised to the aquarium, which rarely takes more than two to three days, the Koran Angelfish is an excellent aquarium fish accepting all foods with rewarding eagerness. Unfortunately it is somewhat prone to White spot disease, but this protozoan infection is easily cleared with appropriate medication, i.e. Cuprazin (no invertebrates) or Myxazin.
