infusoria culture with worms??

[spongebobson]

I was checking my infusoria (paramecium) culture and I saw dozens of tiny white worm looking things.
What it could be? I been using water from my fish tank as a medium for the paramecium and baby powder milk as food.

I sometimes get high densities of predatory nematodes in a tank I use for sorting out pond collections. Whenever I dump leaf litter into the tank it blooms with bacteria and protozoa, and subsequently the nematodes move into the water column to feed on them. There could be hundreds of them hanging vertically in the water column.

can I feed the predatory nematodes to betta fry?
There is also a third inhabitant, it looks like 3 paramecium together, but twice bigger than a paramecium and it swims really fast. any clue?

If the fry are big enough, yes. I feed then to my dwarf cichlid fry.

“looks like 3 paramecium together”? I would need to see this to identify it.
