B&B has two Imperator Angels, one for two months and the other for over a month. With the frozen foods available today it has been easy to keep large angels, as compared to the 90's. I would try corals like mushrooms, GSP, Frogspawn, and Xenia to help filter your water and keep your nitrates down. I bought this blue Face from them and he is doing great.
