Thanks for the comments everyone......as of right now, the Red Tiger runs the tank in terms of the cichlids, but the Jardini you see in the pictures is the actual boss of entire tank, they all stay away from the Jar. The Jardini usually keeps the tank in check not allowing the others to fight....The Dovii is sub dominate and usually just moves out of the way when the Red Tiger comes by, the RT never really goes out of his way to chase the Dovii......When they get older and if I do see constant aggression from the Dovii, I will miss it, but I will probably give up the Dovii before the Red Tiger....
