Awesome looking angel, I hope yours does not turn into the coral eater mine did. I got one as an adult, about 5 inches, and put him and a Red Sea Regal Angel in my 280 on the same day. They both acclimated wonderfully and never had a problem out of either Angel for 8 months. Then I purchased a firefish and didn't quarantine it before putting in my main display. Big Mistake, Fungus outbreak and I lost a Naso, Mimic, Blue Eye, and Achilles Tangs along with the Regal Angel. I almost lost the blueface and two other Tangs but they pulled through. These were established fish I had the Naso for 4 years, The Mimic and Achilles for over 18 months and the Regal and Blue Face were the most recent additions.
As if the loss of all those fish wasn't bad enough. I watched as the Blue Face nipped at an SPS colony. Then did it again and 2 days later I didn't have a single piece of coral. Not one little polyp was left. In less than a week I had lost about $2000 worth of livestock. I was eventually able to catch him and traded him to a LFS where at about 8 inches he was to be the main fish in their display tank. He didn't survive a month in their tank and now I am even more depressed becasue if I would have kept him in my tank he would still be alive and beautiful.
