Is it normal for these guys to display aggression at a mere 2"? My guys will occasionally gill flare eachother and have a quick spar. The loser turns real dark and hides for a minute or two, regains its color, then they're best friends again. I think I might have 2 males. Thoughts?
BTW, no damage is done during the sparring.
