I had a Regal Angelfish when I had little experience and were relatively cheap, it was a gray chest, so given my little experience and the difficulty or bad manipulation of a fish like that because I had no success although, so now I feel quite confident for Being able to keep it, so something that would undoubtedly make a specimen that feeds, if it's gray or yellow chest would be a price choice but would overlook it, the yellowbelly regals are absolutely stunning fishes so if I get a fish like this and that also feed from the beginning that would be to win a good percentage of success, the rest depends on the adaptation process that you are going to take with the fish to your QT tank (because yes, qt always), you must have a variety of frozen foods, sea food porridge and dry food, nori can also help, or anything that may interest you perhaps clams or fresh mussels, I'm not a guy who likes to medicate in qt, alone mind feed the fish to make them strong and fat. I learned from Copps to maintain a quarantine for 3 months to completely rule out any cryptocarion cyst, if everything goes well the DT.
