That original picture I uploaded was the closest they ever got to fighting. The would flare up next to each other and eventually swim away. That was when I had only 2. Once I got more, there was no displaying at all, but it was a very heavily planted tank with lots of hiding spots.
Here was the tank fully planted. I have taken it down now so I only have the fish left.
So you bred these fish?
I once picked up 30 or so from someone on craigslist but they all gradually died off in my 40 gallon community tank over several weeks. I concluded these are best suited in a species tank and with live food being a must.
I should specify that I only have males. No females.
I did not breed them, a friend ordered a ton of stuff online and gave me all of them. My tank was overrun with scuds that were destroying all of my plants. These guys wiped out the scuds pretty quickly!
