For the last week, one of my hermit crabs has been sitting ontop of my Duncan coral. Literally non-stop. It crawls in-between the polyps and seems to just be hanging out. I pulled him off a couple of times and he went right back to it.
At first I was worried he's nibbling the coral, but I don't see any signs of that. At first the Duncan minded him but lately has just accepted it and opens up anyways.
A few questions: is this typical? What's his end game? Is it okay for the coral long term?

I don't know if this is relevant, but I found a few barnacles on the Duncan too. Is this crab trying to eat the barnacles?
