I've had just about every mbuna in my tank at some point. The Kenyi is, by far, the most aggro of the mbuna I've ever had! He's an a-hole! Haha! Still have him. He won't die. He's twice had some kind of eye fungus/virus. Put him in hospital, medicated, and he's as strong as ever.
Original poster asked why? Because that's how they are.
