Hi I have changed my mind and want to have just two cichlids instead of 3. In the tank I will be having 6 tiger barbs,green phantom,pictus and green terror. I would like to have one more cichlid instead of two because it would be a bit cramped if two. I understand that you need one between 6-8 inches I am prepared to forget the tiger barbs i just thaught it would look nice. Thanks in advance
