Parasitic worm or something else?

[Ogpulchra]

I found this in my pea puffer tank and was worried it might be a parasitic worm. I messed with it in and out of water for about 5 minutes and it didn't move. Any idea what it could be? The tank is heavily planted and just has the pea puffers and a small bristlenose pleco. 

*I posted about white stringy poop from one of my puffers not too long ago, but all of my puffers are healthy chubsters and I've only seen normal brown poop from them since then.

If it doesn’t move, I’d assume it’s nothing to be too worried about as long as there’s no other issues with your puffer.

Thanks. I wasn't too worried until I asked about it on a fb puffer group.
