As I am new to the hobby I have found myself staring at my mbuna for hours. My morning routine is now a cup of coffee observation of the fish I feel this might be the best part of my day. Any way I now have 14 fish and have noticed some aggression. I had gotten three new fish last week one being larger then the rest a ob red blotch zebra. When there is a fight even if he is on the total opposite side of the tank he zips over and brakes the fight up. Does that mean he is tank boss? But I have not seen any aggression from him.
