The Siamese fighting fish (Betta splendens) also known as betta, is a popular species of freshwater aquarium fish. B. splendens usually grow to an overall length of about 7 cm,
including fins. Although known for their brilliant colors and large,
flowing fins, the natural coloration of B. splendens is a dull green and brown, and the fins
of wild specimens are relatively short. Brilliantly colored and longer
finned varieties (i.e. Veiltail; Delta; Superdelta; and Halfmoon) have
been developed through selective breeding. Properly kept and fed a correct diet, B. Splendens lives approximately 2–4 years in captivity but 5 is not uncommon. It is possible for them to live up to 10 years in rare cases.

I had a blue and red beta fish that was AMAZING to look at, it had kind of the spindles that some of these have. It lasted 3 times the average life expectancy of Beta fish.
