My blue face angle got scratched some time ago. I have tryed many thing but the sore get bigger and the fungus get bigger. Right now she in a 20 gallon qt tank .I have tetracycline in the tank. 4 days of the tetracycline and it looks the same . I have bought more meds. I got kanamycin,triple sulfa and neomycin. I hopeing the tetracycline helps. I was wondering if there some thing better to use or if i should use one of the other drugs i have. Any help be great.
