I am going to try an acclamation box with my gem for maybe a day or 2 and hope my purple gets used to him...of course maybe I should put the purple in the time out box and let the Gem roam freely
Latter is much better. Unless you remove/isolate the aggressor, you don't reset the pecking order. The acclimation box is mostly a tool to evaluate whether there's likely to be aggression; it doesn't work particularly well to actually curb said aggression.
