Hi, I never like to say certain but I haven’t ever seen a disease break out in this tank. I almost felt my heart sink because I saw my blue tang in that tang scratch but he hasn’t done that for months so I’d say 95% sure he’s okay. I’ve read your thread again on the 45 day fallow periods and I’m pretty confident as well as excited for my tank to be up and running again.You are pretty close to the full term, however are you certain that there are no diseases issues in the tank this fish would be coming from? Often moving a fish will cause a latent disease to start up.
