Well, thankfully he wasn't tangled that bad.....whew!
Within an hour of turning the PH off he had gotten himself mostly out of it. It looked like there was a bit of damage, but hard to tell how much at this point. I'm sure he'll be fine.
I was meeting a friend so I couldn't stay (I would have stayed home if he looked any worse than he did) and by the time I got home he was completely out of it! YAY!
He's moved back to his usual depth in the tank...slightly expanded, but it looks like he found a nice crevace for his 'foot'

. Hopefully I'll be able to get a better look at him tomorrow.
As a side note ~ his name is 'Noodles' (or Noonoos), because that's what my 2 year old niece called him.....the name stuck.
Thanks for the replies,
