I might actually love to get some Tangs as well. Frontosa are Tangs and the compressiceps that are so great in the rocks. They do well together, if raised, together, or can anyway. Holla. Mbuna are so interesting, but every fish in lake Tang descended from a single common ancestor, fact. What does that mean? That they have been isolated as long as the rift lakes have been and every lake is different. Fact. Malawi is not Tang, for instance, for a reason. Blah blah. They like hard water, we have hard water, so that is a natural advantage right there. Discus, not so much. It's not their fault. Soft, slow, blackwater conditions are hard to recreate and make look good in a tank. C'est la vie. It can be done. But I like a bull Frontosa, with some clown loaches and shrimp that he doesn't eat. Ya dig? Or something Tang interesting, myself. Or I can get some more Mbuna. As the profit wills it to be done. What ever you choose. I choose none, personally. But, you know, business.
