The Koran Angel(pomacanthus) is a very beautiful fish to start your aquarium out with.They are commonly collected from the Indian Ocean. They can grow to a maximum of 15 inches. This is another one that like alot of room to swim, and different places to hide. They like to eat a variety of different foods. We were told to watch for agression since we put him in our reef aquarium, but he gets along with everything we have ever had in our tank. Keep water quality high(Sg 1.020-1.025, pH 8.1-8.4) Always keep the tank temp. anywhere from 72-78F.
