I wish mine would host something. Anything. Lol. They are the only clowns I know that have decided to just spend all day swimming all over the tank and have yet to host anything in the tank. I've bought them a nice frogspawn, torch, pearl bubble coral, xenia, st. johns mushrooms.... nope, they are happier swimmin' with everyone else than even hosting a rock or powerhead. They hosted a couple of nems at the LFS for a few months before I brought them home - I think they are just divas and want a nem (which I do not plan to get them for a while if at all). 6 weeks later and they still haven't settled down anywhere in my tank. Silly clowns!
