koi in tank.

Question
I want a baby koi 5-6 inches I have a 29-30 gallon tank I have five goldfish in tehre now just transfered from a ten gallon tank, they are a common feeder/comet/pond goldfish, fantail ans sukabira calico typed goldfish with stright singel tail, I dont want to upgrade tank later on can a single koi get only the size that fits this tank so I don't need to upgrade later?

Answer
Hello,
You will always have to upgrade in tank sizes as a koi grows. You would be better off just buying a 150 gallon tank and then that would probably be a good size for it. You would just be spending more money buying more tanks over abd over again.

Glad To Help You
