Some kind of Slug / Snail ?

[Vanphyre]

This is a hard one, I'm having trouble getting a clear shot with my camera when he is around. Looks kind of like a snail, but its shell appears soft. This guy started off really small and now is about 1" long. Not sure where he came from either. heh.

He also emitted a bunch of white stuff when I just approached the tank. A small little cloud and then it dissolved away.

Im not sure, but a snail without a shell is a nudibranch. But Im not sure if thats what ya got there.

Definately need a better pic. Try searching either stomatella varia or maybe a chiton. Both are awesome algae grazers and a benefit to the tank.

OK, will search away. Thanks for the search advice, I figured the pic wasn't good enough but worth a try. Hopefully can get a better shot if he shows himself again.
