Don’t be mistaken. The above picture is a betta fish. This is what we call a koi betta. This breed have been created by the thailand breeders by mixing marble gene betta with clear cellophane or white bettas. It requires multiple generations of breeding to achieve such colors. Please beware that some koi betta will change colour as they age due to their marbling genes. Therefore it is possible that breeding 2 koi betta will give you solid coloured betta fishes. Highly priced koi betta are thoses that have a single red spot on their head.
