I currently have a 55gal mbuna tank which has been up and running for about 4 months. I am about to set up a new All Male 90gal Peacock/Hap tank. I would like some advice on what particular fish would give me the most variety in color and be compatible. I find many fish that have great colors (reds,blues,yellows) but I am unsure of how different the fish must look to avoid trouble. Alot of the blue/yellow mixes and all red varieties look pretty similar to me so I am unsure. I am not worried about breeding issues just aggression. I also know most people recommend against mixing lakes but I would like to mix in a few victorians for added variety - would that work? Any guidance from more experienced keepers would be greatly appreciated.
