I was wondering what you thought this was and what to do about it - I apologize for the picture quality but this the best my father could do. It’s from his 180 discus tank.
He has 1-2 discus that look emaciated and this was trailing one of them. Could this be a tapeworm or another type of worm / parasite causing this? And if so any suggestions for treatment?
Thanks for the help.
