Okay. Once again, your time is truly appreciated. Thank youSorry - I don't have a good treatment plan to offer you about this. The diagnosis from visible symptoms just isn't clear.
Maybe the issue WAS flukes. If so, the fish should get better in a day or so. However, most gill flukes are egg layers, and FW dips won't stop the infection, because new eggs will hatch out. If the fish improves tomorrow, then flukes are more likely. In that case, you could treat the tank with prazipro 3x, 8 days apart to try and eliminate the infection.
