My anemone has cruised over my zoas, and where it touched them, they closed, but as soon as the anemone passed they reopened. Stonies were unfazed by a quick walk by. I do have the branch of one stony that died due to being in the tentacles of the anemone for days... But what I have noticed gets most affected, is the LPS's, especially torches and frogs. They seem to lock onto each other and neither wants to let go without human intervention
