I am considering getting a Radiata Lion for my 220 gallon mixed reef tank. I know that they are one of the smaller full sized lions, and I understand that as a general rule, lions will eat anything that can fit in to their mouths. That being said, I don't know how big their mouths will be to consider this problem. Will they eat my four inch cleaner shrimp? The only fish in my tank, currently, that I feel would be eaten is my Yasha Haze Goby. That being said, he does hide and is super quick, so I'm not as worried. The only other small(er) fish I have are my ocellaris clowns, my royal gramma, a firefish and that's it. Any thoughts?
