Tiny snails appearing!

[twahl]

I was noticing in my tank tonite that I have a ton of tiny white snails appearing every where. I first thought they might be just empty shells that came in with my sand but they are for sure alive. Does any one know what they are, if they are bad, and if there is any type of critter that will feed on them. I have a lot of larger turbo snails, could they be reproducing? Any help is appreciated.

Turbos and most other clean up snails don't reproduce in captivity. These are probably collonista snails. Look them up. They are generally harmless, though I've heard some people claim they might eat SPS.

In my 125 I added a rock that had a bunch of tiny little snails that only came out at night. Now there are hundreds of them, I only have to buy a few regular snails to clean the glass and sand, because those tiny ones take real good care of the rock.

Collonista are harmless, that you mentioned a sand bed and white makes me think small Nassarius sp.
