Stocking Confusion

[intarsiabox]

I have a 25g mixed reef with 2 clowns, 1 yellow watchman goby and 1 coral beauty. My coral beauty has never picked at any corals and isn't much of a swimmer unless it's feeding time. Usually he just drifts around the rocks looking for any food remanents. I have 2 peppermint shrimp in there as well and nobody in the tank bothers them. My CB is the most docile and well behaved fish in my tank but others have had complete terrors so its hit and miss.
