I have a my angel collect has a adult french, adult emperor, flagfin, and a magestic. I feed a sheet of nori a day and new life spectrum medium large fish pellets with a combo forumal 1 and 2 pellets. Maybe once a week or two I will feed frozen angel food but this is rarely. Both the french and emperor have grown from 2 inch juvs to over 8 inch thick adults in the four years I have them.
