How long has it taken to achieve peace?I have had the exact same issue with my 2 new harlequins and my 2 runners. The runners, especially my chocolate runner was a total jerk. Then the harlequins got big and they started being the jerks. I thought I would have to re-home them but it is slowly getting better. The four of them were actually sharing the pond the other day for a while. It’s just taking much longer than I expected.
