Truth in this! 1 of my black & white clowns 1st tried to host in a bed of zoanthids but eventually moved on to the frogspawn next to it.My clowns love their torch (in a 20g), but they begun to take interest in my GSP, which is beside my/their torch. They like both, but I think they know the torch has a more powerful sting so it would protect them better. But I wouldn't think too much about it, clowns will host in almost anything. I've seen threads/posts in R2R about clowns hosting in zoas.
