what are the "bad" snails?

[dangermon]

I have some snails that look like tiny, tiny turbo snails. First thought was... "Wow, baby turbo snails" but now I know that this is a certain species and trying to figure out if they are bad snails.

Description... small... BB size...whitish and slow moving... any ideas?

(Does anyone have a turbo snail that has lasted over a year? Mine always seem to die after a few months or even a few weeks... )

looks a lot in size, shape, and color to this one... a little whiter but the same... wetwebmedia says Nerites possibly... the last pic is Collonista on reefkeeping.com

I have them and they're not a problem. Well, they're a problem when they plug up a skimmer injector, but other than that they're harmless ime.
