From what I've researched, adding a mandarin should be after a tank is well established with a healthy population of pods. This means that the mandarin is typically the last fish to be added.
Considering that mandarins are peaceful fish, and that in general, fish should be added in order of aggression. How does it affect the success of adding a mandarin after all the aggressors have already gone in?
