I found a bunch of females at Pet Supermarket so I got 4 of them to see if they would pair with my males. Both males now prance around the tank with their fins up and showing all their colors. The aggression has almost disappeared although the females now are butting heads. I am not sure if any have paired off yet, but one of the males and one of the females have no become buddies and jointly are destroying my cuban baby tears now.
