And, in case folks haven't heard of these....I hadn't when I originally got them at one of our previous CCA auctions, here's a pic of the dominant male.
These seem to require pretty average "Mbuna-type" care. I even had them in with some very boisterous Vics and they did pretty well and spawned.
These started out as little medium-dark blue-ish purple juvies and really developed some nice contrast as they matured! Even the females will temporarily color-up this way when they are vying for top of the pecking order.
