how does anyone, if they have this problem...keep fish from breaking their coral? I just had someone in the tank, break some of the new growth off my forest fire didgi! it's the new growth part, and about 1/2 inch or a bit less. this isn't the 1st time, and I think it's my regal tang doing it. she's a buffalo, and is completely reckless. is there a way to help this not happen?
