anyone ever seen Koi? They look like small yellow,black, and white carp. Thats because they are. Do you know what Koi are? Goldfish. Goldfish are very closely related to carp. When in a wild enviroment they grow larger and more aggresive. The hatchery manager probably used goldfish as a feeder fish, more like an aquarium. That makes more sense to me as goldfish are the most popular feeder fish in the aquarium trade.
I understand why goldfish revert to natrual coloration, I have taken courses in genetics, evolution, and right now in ecology. I realize that this does not even compare to the real life expereince that many of you have. But I do have a grasp of How fish feed, where they live, what they require, how they interact, and how thier populations change with time. Understanding these things has been of mine goal for a long time, and will continue to be.
