Parasite! Horrifi! Please Help!

[memder]

I think I have parasite in my tank!

Every time I change the water, some very small white string-like or fiber-like things get stirred up. At first, I thought it was some kind of fungus firmed on the rock and plants and not a big deal.

But today, I watched it care fully, it is moving, like bouncing in the water!!!!!!!! And one of my fish ate it!!!!!!!

I tried to search out what is that on the website, but still not clear.

Does any body know what is that? What I can do to get rid of it?

Sign, I just finished my cycling. If I have to use some med, is there any med that cures the worm and do not affect the beneficial bacteria in the filter?

Thanks.

They sound like nematodes, do the wiggle as they swim, if so they are nothing to worry about. The fish will eat them all and enjoy them.

If you have just finished cycling how many fish do you have in the tank currently, you might be overfeeding, cut back a little.

Sounds like nem's, they aren't pretty and there are many diff ones, but it sounds like one of the harmless ones you have in the tank.
You don't need meds.

Nematodes
