Blue leg crab in Zoa

[Lauramichelle]

I have a certain crab who keeps getting into a particular Zoa. I'm not sure if he's hurting it or cleaning it. I knock him off, but he climbs his way back up. Any ideas? I took this photo at night. Snapped the lights on for the shot. Thank you.

Checked on things this morning. The crab is still snuggled under the Zoa. The Zoa looking pretty as ever. Maybe the crab is hosting the zoa? Lol

He's probably just cleaning up around it..as long as your crabs are fed you shouldn't have any issues with them eating any polyps but if they begin to starve there is a chance they will
