Flukes Or Something Else?

[George]

It does look like some kind of parasites, fluke or something else. have you tried a fresh water dip to see if anything falling out? Also for treatment using prazipro, you need to do it 2 rounds. The first round kills the living parasites. The second round kills the second generation that hatches from eggs after the first round. Prazipro doesn't affect eggs.
