Not sure if I want to mix Acei types. Don't want them to crossbreed. My Walmart doesn't always get fish in, it's not very common, and the fish can sit in the tanks for a while. In the Mixed Africans tank I usually see things like Kenyi, Auratus, and other unknown cichlids. The Yellow Tail Acei is the only one that I've ever seen their, and it still needs some feeding up to look healthy. The last time that I checked, the one Auratus that they had was looking pretty dark, so a dominate male Auratus is a fairly small tank, filled with Kenyi and other unknown cichlids. They also don't take the best care of the fish there, though they've been doing better recently. I prefer to get my fish from my LFS, they take much better care of them. The reason why I got the Acei was because it was the only one there, Walmart is a much closer then my LFS, and the prices for the fish are better. It also came home because I've never seen an Acei in Walmart, and when I put my finger on the glass to point it out, it became excited and begged to come home with me. My Mbuna are way smarter then my Comets were, and my Comets had a pretty good memory.
