I received my janitor package yesterday and when i got home last night, 2am, one of my Zoa rocks was covered by the micro blue legs. I relocated them and this morning they were back again. :huh . Does anyone know if they will eat my zoanthids? Should i move the rock? I think if i move the rock they will find it again.

Thanks

Oh, and they are not bothering any of my other Zoa's, and there is no noticable algae on the rock.
