Butterfly koi have beautiful long fins and seem to just glide gracefully through the water. They are a lot of fun to watch.
How many butterfly koi should you have? Some might suggest having a butterfly koi for every three to five regular koi. There isn’t a standard formula for this because some ponds have only butterfly koi.
The benefit of having one or two butterfly koi among several regular koi is that it amplifies their features and captures your attention.
