Need some advice here....
My cardinal and I have been treating him with API E. M. Erythromycin and does not seem to be working his has been in the hosp tank for almost a month now.
What else can I use to get rid of it?
How contagious is it for the other fish that he had been with prior to me putting him in the hosp tank?
