I want to add a coral beauty to my reef tank, and yes, I do know that they will go after some corals, but I have a way around that. However, I wonder if an Open Brain Coral would be too tempting. My friend has an adult Emperor Angel in a 600 gallon reef tank, but it always tried to eat the brain coral. It was fine with everything else. Will the same thing happen if I get a Coral Beauty in my 125 gallon tank?
