I don't even know if it is myco yet... I don't want to make that assumption and unnecessarily euthanize a ton of fish. Besides, if it is myco, I will probably let them live it out and when they get ill (go lethargic and start bloating) put them down. I haven't introduced anything new for a while except for my petco fish but they are in qt so that's not it. At is point it could just be a bacterial infection which still sucks but isn't nearly as bad as myco.
Today I'm going out and buying clove oil, rubber gloves, and kanaplex. WTH.
