Not sure what kind of lionfish you have, but they all grow very quickly (except maybe the dwarfs), and if you have small clowns and anthias in the tank with a big lionfish, they are going to get eaten eventually. You may want to rethink your stocking plan. They are not likely to peacefully coexist for long.
