If your just trolling (looking to get a reaction by posting this), shame on you.
If you seriously are mixing males together, you need to know your males will kill each other and the female. There not called FIGHTING FISH for no reason. They need to be seperated immediately.
Trust me, I breed these guys, and even brother and sisters will eventually fight and sooner or later kill each other!
It does not matter if they are in a 20 gallon or a 90 gallon tank, males seek each other out to fight. If they have not already, they will, one day you will wake up to find one, both of all of them dead from fighting.
Its instinctive, its part of their genetic makeup, so don't even bother 'experimenting'.
I suggest no one else post replies till this person fixes the problem.
