snail...no shell?

While messing with my lighting and fuge tonite...I discovered this little fellow crawling on the fan...
Bad picture...but it is tiny, it is grenish in color...and has all the actions of a snail...what kind of snail I am asking...and where/how did it come from?

 

that's not a very clear picture, I believe all snails have shells though so if there is no shell then its maybe some kind of worm or sea slug maybe...maybe hitchhiked in on some rock and just hasn't ventured out till now, might want to snag it and put it in quarantine till its Identified

 

Stomatella, good guys. Sort of like small abalone's. If you try to remove they can loose their tails like lizards in order to escape predators.

 

KEWL !!

Thanx a bunch.

 

Check this out to see if it's him.
Stomatella Varia

 

I have lots of snails crawling around without shells. None have ever done me any harm. Pretty amazing if you ask me...

 

I am actually relieved and glad to have found this thread, i have just seen the same thing the other day. My brother saw it first and said you have some snails without any shells. I was like,no I don't. Then the next day I saw two of these guys crawling around. One on the glass and two on the lr. They just seemed to be eating the algae and not bothering anything else. So now I know what they are. thanks!

 

I am thinking Stomatella also. They usually roam the tank after lights out, check it out. You may have more.

As stated though, they are harmless.

 

they come in on liverock and also they lay eggs in algae so they can come in that way as well.they do reproduce so you will have more eventually.they have a half shell if you look closer.
