I just added a majestic to my 180 gallon system two months ago and he is doing very well. He was eating from the first day and other than being very shy at the beginning he was a very solid fish and adapted to the tank very quickly. Mine eats like a pig and takes mysis, plankton, angel formula, new life spectrum pellets, and loves nori sheets.
The fish is getting bolder by the day, I will try to get a decent pic. This fish is in fgull adult colors, about 4 inches and gets along great with my tangs and rabbitfish and pretty much ignores all of the other inhabitants. When this angel was first introduced it was extremely shy and I really stayed away from the tank for a few days and let it settle in. From everything I have read and my recent experience with this fish indicates it will generally do well if you get a healthy, feeding specimin and provide a good environment. The majestic is just a beautiful angel and is one of the smallest and least aggressive Pomanthus and is also one of the more reef safe large angels. About the only negative is its shyness, they arent nearly as bold as an emperor for instance.
