Im seeing crazy growth in my Orinos. They have grown about 1" in about a month, and have put on really good girth. Frozen krill pieces, market shrimp pieces, ocasional frozen bloodworms / glassworms, and live rosies, ghost shrimp or live bearers once a week. They just recently started taking freeze dried krill, hopefully pellets soon. They have put on enough weight that I am about to reduce their feedings, power feeding for too long can actually stunt growth. I think variety is the key. I may start something new here soon....fresh cut pieces of salmon with the skin. Salmon skin is a major ingredient in color enhancing foods.
