What are these?

[sczu]

Hi all .
Can anybody tell me what kind of worms these are? I noticed them when filling my tank after my weekly water change.I don't see them on my fish but the fish seemed stressed the last couple of day's.The worm's are the thickness of thread and the longest is about 1/4''.They seem to mostly be on the bottom of the tank.The picture of the clump of them is inside my diatom filter.How can I get rid of these? Thanks in advance.

they are most likly harmless little scavengers

to get rid of them keep up on water changes and feed your fish less!!

They look like Nematodes to me.Usually harmless like planaria.Usually a sign of overfeeding.Just up your w/c's and back off the feeding for a bit.

great, i just found these in my water, and was going to start a post. i think i got mine from putting in an old air pump that was sitting in water though.

Agreed with all of the above...reduce feedings and increase water changes.

Agreed with above. Harmless but annoying...
