Small white snails

[Drock169]

there are a few different types of small snails that occur in our tank. 1 is a micro turbo snails whos species name escapes me right now, but its good, it will graze on microalgae and multiply your tank. Another one is the pyramellid (spelling?) snail, which is parasitic. The obvious difference is the shell shape. check in the reference library forum you might be able to find something there.
