Can clownfish kill coral?

[daniella3d]

I got an anemone but now if the fish are going to go in it is another story. It's huge! It did not look so big at the store but in my 75 gallons it's a monster, about 10" across. I think it's the long tentacles, not sure, but it is one of the type that stay in the sand and are supposed to host clownfish.

Now beside the photo tric, any way to make the clownfish adopt it?
