Koi in Aquarium

I would like to have Koi in an aquarium. I'm getting a 29 gallon tank and filter along with other stuff since I don't have a pond or have the money for it. Is there anything else I need to do to keep them healthy? Like vitamins? -Sydney Just make sure that you have adequate filtration on your tank and you feed them a good Koi food. Maybe plan ahead and find someone that could take them if they outgrow your tank. Share: Del.icio.us Digg Reddit
