BTA Question

[Marlin65]

So I picked up a BTA and found a nice spot for him.
He has moved though I am not sure why the spot I picked out should of been good for it. He looks like he might be splitting so maybe that has something to do with it.
He moved to the underside of this rock in this cave where I can't get to him.
He can't be getting a lot of light there and I am wondering if I should pull him out or just leave him for now?
I never had one before so am not sure if this is normal for them.
My Parameters are good so don't think it has anything to do with that.
Anybody know if this is normal for them.:question:

Most anemones will get up and wander wherever and whenever. There's not much you can do about it. It's kinda like trying to take toddlers to the mall.
