 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.  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
