Turtles are in fact herbivores and carnivores so they can possibly feed on koi fish
They eat fish food. You can choose to not feed them at all because Koi are bottom feeders, and the more you feed them the less algae they will eat. Feeding koi is done only for entertainment reasons. Though if you do feed them, we recommend not feeding fish more than once a day. The fish have plenty of things to nibble on in the pond, and the more you feed the fish, the more waste they will produce. The only time you have to feed your koi is when a new pond is installed, because there is no algae for the fish to eat. Also you must feed your koi fish less in the wintertime (depending on your area). Don't feed the fish when the water is under 55 degrees because the fish metabolism is slowed down and won't be able to process the food.
I feed mime freeze dried blood worms
Probably the same thing you're feeding it in when it's in the pond.
The size of the koi will depend on many factors such as what type of koi it is, how much and what you feed it and the size of the aquarium or pond you keep it in.
No they do not change colour if they eat golden coloured fish. I also wonder why on earth anyone would consider feeding live fish to Koi carp.
1. You might get other Koi in a fight 2. You can leave a mess in their home, and might make them find somewhere else to live... which changes a lot of things around.
You only need to feed them the amount they can eat in three minutes once or twice a day. People often overfeed fish but the truth is the fish are not very active in a fish tank cause they have a limited amount of space so they don't need a lot of food. It is never bad to put not enough food in because you can add more but when you add too much it is hard to get it all out. If you overfeed them than the uneaten food sinks t the bottom grows fungi on it and heavily pollutes the water.

Koi fish can live in almost any country. Koi are thought to be originally from Japan. Many people have outdoor fish ponds in which Koi are the dominant fish.
