Thread: enriching environment and food

Hi I have 3 koi in a 4 ft deep concrete tank. I feel sorry for them because I think it must be a bit boring for them. I bought some big plastic pondweed plants because they seem to destroy anything living.

I want to make their lives more interesting but I don't know how. They are quite big - may a foot and a half long - so I don't know what to give them to play with or make life more interesting, I thought maybe something to swim through but as I said they're quite big.

Food wise I give them, as well as their pellets, snails from the garden (I shell the big ones), half corn cobs that somehow they manage to get the kernels off, wedges of oranges that they chase around and love, I've had intermittent success with lettuce and still haven't really worked out which ones if any they like. They won't eat chinese leaf. and they don't like carrot. If anyone else has any ideas of things I can do to make their lives better I'd love to hear them.

thank you for that. My pond actually does have a setting that would enable a flow of water for them to swim against but I've never used it so I will see if I can do that. And I never thought of cheerios though I think mine would eat any breakfast cereal with relish.
