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,
