He seems to be doing better. That looks like columnaris. Do a big water change and start the Jungle Fungus Cure according to package. Disinfect any nets or things you use in the tank as it is very contagious. Continue to keep me posted.
Yes, it’s Blaze. How do I safely disinfect nets? Ok, I’ll start the Jungle Fungus Cure today. Should I wait for tomorrow to start? (I’m only asking because I don’t want it to react to the other medication.) Also, is it ok to put my carbon back in to remove the yellow color? Or do I still need to leave it out for the JFC?
