    I noticed tonight on the inside of the glass, hundreds of small white dots moving about. They seems to be longer than they are wide, but less than 1mm in length. They also seem to be capable of moving rather quickly.

    Any ideas what this might be?

    EDIT : I will attempt to gather some of these tomorrow and get them under the microscope.

    at worst, they might be flatworms.
    hopefully not.

    It could also be copepods

    are they moving on the glass, or are they free swimming?

    They don't appear to be swimming, they are moving around on the glass. I did a quick search for flat worm images, does not quite look like that.

    I think its called stomatella, algae eating type of snail. They eat algae like crazy.

    Agree. Also not sure of the name. I added 2 turbo snails and about a month after that also noticed the small white dot all over the glass. Ot turn out to be turbo snail babies

    I highly doubt that these are snails because of the speed at which they move.So possibly Copepoda. I have had them and still see them in my tank if i look closely enough unless my red ruby doesn't get them first.

    Having looked at Google images, I don't think they are snails either. Too quick to be snails.

    How long has your tank been running for? It sounds like pods to me. I had the same in my tank just after cycling the tank. Early life stage of pods.

    Stomatella moves extremely fast, i am not sure that they are snails but they look like snails without shells.

    Think its pods. I also see them on my glass when the algae starts growing on it.

    I have not had a chance to sample and view them under a microscope yet. Will likely get around to it tonight. I will also try borrow the digital microscope from work,so with a little luck we will have some pics tonight.

    The tank completed its cycle two weeks ago.

    So it turns out these little dots are small cyclops. I feed frozen cyclops to the bangai cardinal, so I can only assume that somehow some of these cyclops survived the freeze, or maybe some of the eggs did.

    There are quite a few other critters also to be seen under the microscope. This one I found on the glass. No idea what it is.

    Here is a better one of a cyclops.

    Then there are some other random pics I took with the digital microscope. I was amazed to see how much life is in an aquarium. Everywhere you look, on every surface, there is something moving or squirming or oozing.

    No idea what this is, but I have plenty of these that came with the Fiji live rock.

    There are also a few of these tiny tube worms all over. Does anybody know if these get bigger, or are they a smaller variety?
