Also known as the marble betta, the Koi betta was accidentally bred when trying to breed the first butterfly black betta. Named the koi betta for their resemblance of the Japanese koi fish. This fish is known to change colours as it matures and is perfect for the beginner aquarist to the experience betta enthusiast. 

Depending on the fish itself, they can be kept with other peaceful tropical fish. Betta fish are a labyrinth fish, meaning they have evolved over time to have an addition organ that allows them to breath surface air. 

A golden rule of keeping bettas : Don't put two bettas in the same fish tank unless you are ready for a fish fight.
