they usually come out at night, but 2 of them kinda poked out this afternoon, and it looked like there were spitting something out there mouth, almost looked like smoke!! it was weird!
there under an inch long, and have a thin flat shell on there back.
are they dongerous? what the heck were they spitting out??? it just looked like a little white puff or cloud come out of there mouth

It looks like a nasarius to me. They are good. Usually just clean the substrate but will come out when you feed.

Hard to tell from the pictures what types of snails they are but nass. are a very good snail. I assum the "smoke" they were spitting was sperm or eggs something along those lines.

is the shell covering the whole body like a regular snail or is it just on the back?? from the pics it looks like its on the back, meaning it may be a stomenella (spelling?) snail , which are harmless
