Ok so things have gotten very interesting as of today.
I haven't been able to update as mentioned above, between personal stuff and the nem being on the back wall, but today I was quite surprised.
The nem was hanging out in the back wall for a while, then jump over and was hanging out against the large rock that was blocking my view. I was able to see him somewhat better still and feed him so all was well.
As I was just feeding the tank, I went to check in him and give him a chunk of squid... and he was... well.. gone.
Looked all over, very puzzled. Then I saw a small piece o him juuuust sticking out of the backside of the rock.
The nem has squoze(real word?) himself into the rock!?
A piece of him the size of a nickel is hanging out.
What the heck do I do now?
I'm assuming if he gets hungry he'll eventually come out, but then again, when I first saw him, he was buried under rock, stark white and small.
Maybe he'll never come out.

I didn't want to put a piece of squid on the exposed part because I don't want him to think he's going to get food while stuck in there.
I'm pretty sure a little red emerald crab lives in that rock... they don't eat carpet anemones do they?
What... the... heck.
