When I had mine, it was a great fish and never bothered my dwarf potters angel, clowns, wrasse, mandarin or watchman goby in a 72g tank. I kept the entire reef tank well fed and spot fed the fuzzy dwarf lion. I feed mine krill and here also would eat the occasional mysis shrimp that floated by. So it is completely possible to keep them all together, but it's hit or miss with each fish. I had mine for years before selling the tank.
