Please Help With Fish Dz Diagnosis

[dbarcorals]

Hi all,

My powder brown tang is displaying some unusual lesions throughout his body which I thought was at first Ich. However, the lesions look nothing like ich where they look like well demarcated white dots throughout the body. Instead, I see stringy/fuzzy white lesions throughout the whole body (fins, mouth, body) and I also see him scratch. I currently have him in a copper QT tank, but if this is not ich, I may have to change the choice of treatment. Because of the fuzzy looking spots, I think it could be some sort of bacterial/fungal infection that I am unaware of. I have also considered lymphocystitis but I don't really see many "cauliflower-like" lesions around the fins. I would really appreciate any help with diagnosis and treatment. I have included two pictures of the powder brown (not the best pictures but the best I could get after spending 15+ mins trying). The pictures may help show the lesion distribution, but in person, the lesions look much more stringy/fuzzy and a lot more than seen in the picture.

That isn't Lymphocystis. How long has the fish been in full copper dose? You should consider dosing with praziquantel for flukes.

The powder brown has been in copper for almost 2 weeks now and I see no improvement or reduction in signs. Can flukes cause lesions that look like what has been described?

Yes, the secondary diagnosis would be flukes. Treatment 2x with praziquantel about 10 days apart, with good aeration.

I will try a freshwater dip to see if there are flukes that come off the fish. If so, I will continue with praziquantel treatment. Thank you so much!
