Tiny, tiny white 'bugs', what the heck are they!?

[20 20]

My boy has a 75 gallon discus tank with 7 discus in it, and one small motoro (I think) stingray. He's been treating the tank with 'Pemifix' and 'Melafix' (again, I think that's how they're spelled) for about a week and a half for fungus on the stingray. Well, tonight he notices a bunch of fine 'stuff' in the tank. A lot of it, swirling around in the water. No idea what it is, he stick on a HOB filter stuffed with floss to try and filter it out. Oh, yeah, he runs an XP3 on the tank. Not sure of the water parameters, he doesn't measure them very often. I think PH is around 7 to 7.5, but I could be wrong.

Well, a couple of hours later, he yells "Dad, come here! They're alive!" And sure enough, all these floating things in the water are little white wiggly 'things'. Very small, gotta watch real close to see them move, but believe me, they're alive. Does anyone have any idea what the heck they can be, how they got in the tank, and how can they be gotten rid of?

Thanks!

There are any number of little swimmy things that could be in the tank. They are usually harmless. The usual cause is overfeeding and lack of maintenance. Increase your gravel vacs and cut back on food. The cleaner water will be good for the discus and for the fungus on the ray.

at first i was going to say it is from the floss. Often when you add new floss their is a little bit of "floss dust" that gets out a is floating all around. If you are sure it is alive I have no idea...
Maybe if you could, get a pic

I agree with apocalypse_gold. Its likely a species of roundworm or flatworm that result from a high level of nutrients in your tank from overfeeding, lack of maintenence, etc. Correct those issues, and they will go away.

Thanks for the replies. I think it's 'planaria', a small flatworm:

My boy does like to feed alot, I'm constantly telling him he overfeeds. Maybe this will convince him that, yet again, DAD IS RIGHT!!!

The one's in my boys tank don't look like that, I'm sure they're some kind of work, planaria or nematode, etc. There were quite a bit less of them after I got home from work yesterday, the HOB seems to be working. He change the floss, it was quite dirty, and the water is quite a bit clearer.
