He was in the copper treatment for about an hour and ended up on it's side. So I think that's the problem. I took him out and put him in a bucket with DT water.This has become a bacterial infection and needs to be addressed first. If not mentioned. . . Best treatments are :
Kanaplex by Seachem
Neoplex by Seachem
Maracyn 2
*** One of these - Not all three at same time and remember to add aeration during treatment
I do not have any saltwater left. I have Kanaplex I can treat with and I can add aeration.
