What Is The Difference Between Koi And Butterfly Koi?

Koi and butterfly koi are two types of ornamental fish that are popular in aquaculture. They are both members of the carp family and have many similarities, but there are also some important differences between them.

Koi are native to East Asia and have been bred for centuries for their beauty and grace. Butterfly koi, on the other hand, are a relatively new hybrid that was developed in Japan in the 1970s.

One of the most noticeable differences between koi and butterfly koi is their coloration. Koi typically have a single color, while butterfly koi have a pattern of two or more colors.

Butterfly koi also have longer fins than koi, which gives them a more graceful appearance.

Another difference between these two types of fish is their behavior. Koi are generally peaceful and can be kept together in a pond without any problems.

Butterfly koi, on the other hand, are more active and may become aggressive if they are kept with other fish.

Both koi and butterfly koi make excellent additions to a water garden or pond. They are both beautiful fish that are sure to add interest and enjoyment to any aquatic setting.
