Clean water, healthy diet, warm temperature and the occasional expression of aggression will help a bit but in the long run it's all about genetics.

Well a varied diet is vital. Krill, raw shrimp, grand sumo (staple), Hikari Bio-gold, frozen foods, live worms, brine shrimp, ect. I can go on and on but my main point is they need a varied diet. It will also keep them interested in their food.

The KOK comes down to genetics. He looks like he's got a nice one coming along.
