Oh yeah man, my Huma Huma(Herman) is a blast. He causes trouble then gives me the "look what I did" look. As for a clean up crew....well I haven't found a Hermanproof crew yet. Brittlestars work for me. He nipped once and learned his lesson. And don't be too surprised when you get home and you can't see from one end of the tank to the other. Mine loves to dig, get a mouthfull of sand and spit it out at a power head. Its and aweful mess, but he is a damn cool little fish. I have never had a problem with him bothering my clown or my LMB. He is good with Anemones too. Just my experiences.
