I'm picking out my baby koi and albino channel cats tonight, I'm going to grow them out over the winter and spring, and by summer I should have the pond I'm putting in for my mom finished, so they can go there. Any suggestions to make these suckers grow HUGE? I'm feeding them Hikari Koi Staple right now, and plan on moving them to Hikari Koi Growth as soon as my order comes in.
