I've got the flame angel for 1 month and he is awesome. I got RBTA, Torch, Shrooms, Xenia, Various Acros and Monti, he nipped at the acro polyps several time but never likes it and stop ever since. Now he swim around picking on LR and eating HA. He is really active and has great personality. I will try Emperor Angel next week, and hope i got the same luck (finger crossed).
