Anyone know what this is

This is in my quarantine tank that I have fish going into tomorrow. It had to have come off the foam sponge I put in from my display tank sump.
It's a worm type thing and it's leaving a stringy trail wherever it goes
Will it be a problem?

When in doubt, take it out. Especially if its in a quarantine tank. I doubt it's anything that would be harmfull to your fish, but why risk it? Best bet, take it out, put it in a plastic container to get some better pictures of it

Looks like a spaghetti worm. But like said need better pictures.

I think it is a spaghetti worm looking at photos of them online. I do know i have them in my tank just never seen the actual worm part.
I'm at work for the night but I'll get it out in the morning and get better photos.
Thanks guys
