Hitch hiker Sighting and Identification

I noticed this little fella in my wife's aquarium the other day and thought it might be a nudibranch or nudibrach? I've seen it spelled both ways. Is there a difference?
I realize there are too many types for a positive ID and the photo is a little blury ( The camera had a hard time focusing through the glass) But I was hoping someone would look at it, and chat, and give out his or her opinion. ;D It's about a half inch long and I do not see a shell. I wish i could get this expensive 3.2 megapixel camera to focus like I want it too >
Let me know what you think... Friend or Foe to a combo fish and soft coral tank.
TIA  Jim

JIm,

From what I can see it looks like a Nudibranch.

Reminds me of the feeding end of a filter feeding cucumber

 

Don't know what the creature is because I'm just a "Newbie". But, for the focusing problem with the camera - are you using the macro mode of the camera? I use the macro mode on my Nikon and sometimes have to move the camera either up against the glass or a little distance away for the autofocus to work.
