I purchased 70 cardinal tetras and placed them in quarantine. 62 died within a couple days from what looked like the "neon tetra disease" it went away and left 8 fish. I know it's crazy but I'm now trying to save the last couple of fish. they have white spot. I've used tonnes of protozin and it's not working. I'm now trying esha 2000 because maybe it's more fungal not exactly whitespot? but they are all covered in it and theres like 6 left now. I think they have a few hours left. temp is high and there is salt in there. since they have such little time left do I try mixing the protozin and esha 2000 for a final last attempt? thanks guys
