Colors
Bettas have been affectionately nicknamed "The Jewel of the Orient" due to the wide range of colors which are produced through selective breeding.

Wild bettas only exhibit strong colors when agitated.^{[citation needed]} However, breeders have been able to make this coloration permanent, and a wide variety of hues breed true. Bettas come in a variety of colors, such as red, blue, turquoise, orange, yellow, white, and green. Most are slightly iridescent, and can appear to change color with different lighting or viewing angle. Breeders have also developed different color patterns such as marble and butterfly, as well as metallic shades such as copper, gold, and opaque.^{[citation needed]}

Breeders around the world continue to develop new varieties. Often, the male species are sold preferentially in stores because of their beauty, compared to the females. Recently, breeders have developed in females the same range of colors previously only bred in males. However, females never develop fins as showy as males of the same type and are almost always more subdued in colouration.

The true albino betta is a 'holy grail' that has been feverishly sought after since one recorded appearance in 1927, and one in 1953. Neither of them were able to establish a line of true albino betta. In 1994, a hobbyist named Tanaka successfully bred it
