Thanx, Galaxie, that's all I wanted to hear. I just wanted to know if salt harmed fish but nobody would tell me. Your question, am I treating the fish? Well I have decided to humanley euthanise 'SweetPea' as I like to call her, bacuse her condition is probaly too far in to be treated. I believe it was an interbal infection , yes, becuase there were no pysical signs of illness on her body. How do I go about treating all of the tank that might have got infected to? Please help!
