Thank you very much for your response! I feel so much better now knowing that you also agree doing a full round of Kanaplex is a good idea. I’m not familiar with Metroplex, but I’m going to check right now if it’s available locally so I can start it right away.Hey there. Apologies for not getting back to you sooner. In all honesty I would go ahead with a full Kanaplex and Metroplex 3x doses 48 hrs apart at the same time-that should treat any internal and external bacterial infections as well as internal and external parasites. If that does not work I would look into consulting with a fish veterinarian or trying Potassium Permanganate (very strong antibiotic that vets use) and flubendazole (the strongest de-wormer I have come across to be safe for fish).
