Just remember what happens to men when you have several males and very few females? same with fish they all want to win the girls!!
most peacocks are fairly mellow but can be very conspecific aggressive..
OHH and since you have that Johanni you will want to stay away from similar colored fish,like Demasoni..
I made that mistake and bought a Johanni and put into my tank with my Hybrid Demasoni and he nearly killed that Johanni in just a few hours, had to give the Johanni to my mom..so be careful of what colors you put in your tank now..
Oohh yea def Scott....its just like this for now....will be getting rid of
