Yes, my Lwanda males all hit 6 inch size. I have no problem housing alto comp with my CA/SA, here is an earlier video of my 75g. http://www.youtube.com/watch?v=HsTDjx0E1pg Unfortunately, I lost the entire colony of comp to chemical poisoning and have to start all over.
Your choice of fish makes a difference whether the mix will work or not. For the large CA/SA, I only picked the most peaceful CA/SA like Green Terror, Vieja and Thorichthys species. For small Africans, I picked the mildly aggressive haps and Tangs and avoid Mbuna. For big fish I keep single males only to avoid pairing aggression. For dimulative Tangs, I keep colonies that hide and breed in the rock caves. Interestingly, the big guys have acclimated to and don't eat the fry which gradually emerged from the caves and compete boldly for food side by side with the big guys. The CA/SA, haps and Tangs each pick fight among their own kind, and occasionaly the Haps pick fight with CA/SA, but never the other way around. It's amazing to see a 5 inch Eureka Peacock chase an 11 inch Sysnpillum.
