I think that "starting" them in a 120 is a mistake, I have thought long and hard about a mix similar to this, but, mine is planned for a 600. Moving pikes changes the dynamics of the social ladder so to speak, "bonded" pairs don't usually make it through moves like that from my experiences. Another consideration of the limited space is that the fish act differently based on the space they are given, less space usually means more aggression.
Thats just my two cents, either way, I would like to know how it works for ya, I am trying to make mine work this summer, plywood tank, 10' x 4' x 2' DIY.
