Cool, thx
It's a 100g tank
I am able to swap in and out this FH with my other FH (fader) and the Reddevil in the avatar. The Fader and Reddevil are currently in their own breeders' tank with their lady friend. For now, I only allow a dominate male in the community at any given time. I believe I can put all of them together and most likely they will fight, but they will settle in a day or just hrs. I just hate looking at torn fins after the fight! If I ever do, I'll post pix.
Beside the one dominate male setup, the other tricks are to grow them up together (just like Dragonfish18 said) or to clutter the tank with lots of fish so that they can't be territorial. In either way, just can't have like 2 or 3 of these monsters in the tank. 5 seems to the min.
