I just introduce a 2 inch Flame Angelfish (Dwarf) to my reef tank. He acclimated well and is eating! However, one of my fish, Powder Blue Tang - 4 ½ inch, was cornering , biting, and chasing him (Flame Angel) as soon as he saw him! I immediately remove the Powder Blue from the tank. However, I would like for both spices to be in this tank and by nature are compatible. Does anyone have any ideas if there is any method or technique in order for these two to do well together??? Thank You!
