This is a group of angels that get very large and, for the most part, aren’t reef safe. Although a number of people have been able to keep them in reef tanks, most will pick at corals, clams, and worms in the tank, so if you introduce one into your reef tank, they need to be carefully watched. For the most part they do very well in FO or FOWLR tanks, but they need tanks that are at least 6 feet or larger. They need to be fed a large amount of greens and meaty foods which will put a heavy load on a filtration system. It can be very hard to get this angel to eat at first, but once started they usually do very well. They do get large but smaller adults can be found. Care needs to be taken with tankmates, especially other angels, as they can be on the shy side and easily bullied. If you listen closely you will hear them making grunting sounds, especially when chasing other angels.
