I'm just getting ready to start my goldfish fry on a bloodworm/vegi/flake diet and was wondering what type of lettuce fish prefer? I have always fed my fish cucumber and peas but never lettuce. I have thrown some into my koi pond but they never seemed too interested in it. I heard goldies prefer lettuce over other vegies. I have always fed goldfish fresh cabomba in the past, but this year its getting hard to find in the wild.
