I bought a condy and a tomato clown. No hosting as of yet. I've been feeding mine mysis when I feed the fish too. My tomato shows no interest in hosting after being in there for 4 days with him, but time will tell. I actually want to get rid of him, because I want to make sure that it doesnt' consume any of my reef creatures. Because it's not naturally a host for fish, it runs the chance of eating anything that trys to host it. That's been a big turnoff for me. However I heard that green mythax crabs host it or something like that....
I'm hoping that now that my tank is stable, I don't have the melting problem. If I do though, at what point should I say to myself "Cut and Run" (Colbert report plug) and pull him out? He looks okay now, he's starting to color back up to purple again from his previous white state.
