My sunburst wag platy has some weird string coming out of her butt. She's plump but I don't think she's pregnant. I think it's poop but want to be sure
Possibly constipation they can build up some absurd bowel movements! or internal parasites. You could try feeding pees and if it continues being stringy I would consider treating for worms/internal parasites.
