Black Worms infestation

Hi all,
All of a sudden I have an aquarium that is infested with thin, long worms. After this my aquarium has become extremely cloudy and nitrates gone up. Right now I had to change all white pre-filter to remove alot of worms but i still have in aquarium. I also did a 10% wc, i will try to do that every day maybe I eliminate them. Will they kill the fish? Practically I have catfish only in this aquarium. How did they come in the aquarium?

Thanks for help

Are they swimming or in the substrate?

If they are the blackworms I'm thinking of, then they overpopulated bc you overfed, and the overfeeding and bioload caused the nitrates...

Try not feeding your tank for a few days and change some water. Can we get a picture?

I might want you to mail some of the worms to me if they are true blackworms.

I will try to get some pictures tomorrow.

I am feeding 3x algae discs and zucchini for my bristlenose. Also i have some juveniles and do not want to stop feeding them.

I am doing 10% WC daily may be I solve the nitrate issue.

I found them in the pre filter and do not have any gravel.

it seems that they are mosquito larvae. Are they bad for bristlenose?
