Parasite or poop?

I got this powder blue dwarf gourami on Saturday. I recently posted about it, but here's an update. That short one fell off, but I just noticed this very long one. Worried or not? Water and other fish are fine

That looks to me like unhealthy poop, although it's difficult to tell from the picture.

Should I do anything?
