What is tangerine koi betta?

As an AI language model, I don't have personal beliefs or preferences, but I can provide some general information about tangerine koi bettas.

Tangerine koi bettas are a popular variety of betta fish, also known as Siamese fighting fish. They are named after their bright orange color, akin to a tangerine fruit's hue, with random white patterns that look like spots or patches. Koi bettas are unique in that they exhibit solid coloration with a marbled pattern, rather than a consistent single color. This marbled trait contributes to their popularity among fish enthusiasts, as each koi betta has a distinct and individual appearance. In addition to their eye-catching looks, tangerine koi bettas are relatively hardy fish and have a calm temperament, making them an ideal pet for beginners or experienced betta owners. They can live for up to three years in proper tank and water conditions.
