Not annoying at all, I just thought it was pretty clear that the fish won't re-infect itself - if it has the lympho virus, it has it for life. The lower the stress levels, the greater the chance that the virus will stay in remission. Not much that one can add to all of this, as not all fish will react the same due to all the variables that involve stress levels in a glass box, and the individual immune system of each fish that gets infected. Good luck.
