Thanks for the insights. Keep in mind that this is a huge old male green
Severum, in a tank with a dozen others, all smaller but mature fish. None of
the others has any symptoms, so I'm guessing it's not the water quality. He
continues to be the most aggressive fish, and eats well. As I said the
treatment worked perfectly and he was fine for months, before it just now
returned. My guess is that it's more old age and failing organs, than any
infection. Will try again, to help extend his life.
