Internal parasite?

[Alwmh4]

so I just fished out a white string from my aquarium. It stayed in tack. Bout 7" long. Could this be constipation? Behave no idea which fish it was but I suspect the tang

Thanks!

White stringy poop is a symptom of intestinal worms. Treat with metronidazole (you can soak it in fish food if you use Seachem Focus). But I would wait until you see it hanging out of a fish's anus before treating (to be sure.)

Prazi pro is what I have on hand. Would that suffice?

Prazipro works in most cases on intestinal worms.

How long do you suggest I do this treatment? Couple corals are suffering I'm assuming from oxygen issues though I'm doing everything poss to help with that. Did one treatment in 13th but forgot uv filter and skimmer for about 30 min after treatment. On advice from Hikari I did a water change on day 3 and second treatment on the 17th. I'm getting ready for another water change today. Should I do another 7 day cycle? Run carbon and skimmer for today before retreating??

Yes, I would dose Prazipro one more time (today) to be sure you get any hatchlings before they are mature enough to lay eggs of their own.
