The red patch is gone completely it was gone the day after I moved him to the other tank. Do you think the infection is still there just not visible? Now this nori can other fish eat it too if I move him back to the display I don’t have much more time with my alt. Tank I could always try and set up a smaller one.
I’ve had the tang for probably 3 months now and it literally popped up in a day I pulled him right away thankfully I had the empty tank running in my garage. The reason I thought maybe stress was the fact it went away once in the other tank. Now the white line and white around the eyes did start sooner but now that I think about it. It was probably about a week after I threw a bag of carbon in. SmhOther herbivores and omnivores will eat Nori, highly recommend you feed it if you are not...
As for the bacterial infection, I’ll wait for @Humblefish to answer that. I was lucky I caught the bacterial infection on my tang during QT so I was able to treat immediately.
