    Hey everyone,

    Found this little guy cruising on my glass tonight. It looks exactly like a miniture version of a astrea snail. Don't know how this is possible though because I haven't had any snail in my tank for about 2 months now. Is it even possible for this little snail to reach full size in a tank. The snail is tiny, probably between 1-2mm.

    Here's the best pic I could get:

    I have 100's of them in my tank. They appear after lights out, and disappear again the next morning.

    They have never grown larger than about 5mm in size, so I suspect that they are a completely different specie than the Astreas they resemble.

    They are algae eaters, and have not proven to he harmful, so they are very welcome in my tank.

    Those snails are called collonista. They are very small, and are beneficial to your tank.
