Mysterious tiny creatures

[Plowboy91]

When I was cleaning my tank yesterday I noticed that there were groups of very tiny bubbles on my driftwood but upon a closer look they were microorganisms that are swimming around my driftwood and tank. They are about the size of a pin head (or if you would take a pen and make a dot on a piece of paper), are white/clear in color, and seem to have flaggellum which they use for movement (and I think eating as well). I have not added anything new into the tank for over a month so they didn't hitch a ride from a pet store. They usually swim around my driftwood, some shells I have in the tank, and a spot of algae that is on my glass.

What are these little things, are they going to cause me any problems, and how can I get rid of them if they are a problem?

I tried to get some pictures but they are very small and fast so the pics aren't the best. There are no bubbles in the pics, only blurred images of these microbes.

Any help would be great. Thanks!

Looks like planaria to me. Harmless to the fish, usually caused by overfeeding. How often are you feeding?

Looks the same to me too, just cut back the feeding a little do a water change and let your fish handle the rest of the clean up.

I am feeding twice a day but I am probably feeding too much so I'll reduce it and do some cleanup/water changes. thanks!

That should do the trick. Feed only as much as the fish can consume in a minute or two.

After talking with someone else they said that planaria are not oval or round, they are more hammer shaped (for the lack of being able to draw) I also sucked a bunch out of my tank when I did a water change and I am feeding much less but they seem to keep reproducing. Do I need to be more patient with this and if it's not planaria, what is it?
