What should I feed my Koi & Goldfish, should it vary based on season? I fed my Goldfish mainly cichlid pellets last year, and tried to get them to eat krill w/out success. I read somewhere that they will eat brocoli, and fruit, anyone try this? I also plan on putting many juvnille Green Terrors in my pond for the summer (breeding GT's), will they be eaten by Koi/Goldfish?
