I got my champs at about 2" and like I said there about 7" in a year I think there growing pretty quickly. I feed my NLS 1mm cichlid formula, Hikari cichlid gold 3mm, and frozen cubes of brine shrimp and blood worms everyday. When they were younger I was feeding them minows and small goldfish, but now I have so juvi's that are in the tank that are about the size of small goldfish so I try to keep them out of the hunter mentality.
