I happen to have a 110G SW. And yes I also have the volitan in there. Along with a hippo tang(dori), engineering goby, maroon clown fish(sorta like nemo but a bigger version), starfish, lobster, cleaner shrimp and many other critters/fish I don't feel like mentioning.
Oh and you don't actually have to "hand feed" the lion. You can, but all I do it drop a silverside in the water around him and he takes care of the rest.
