In the wild
In the wild, bettas live in rice paddies, canals, and small rivers.[2]
Betta splendens is listed as vulnerable on the IUCN Red List.[3] This means that Betta splendens may become endangered soon.
Appearance
Males are more colorful and usually have larger fins than the females.[1] There are many color patterns and fin types of Betta splendens. Female bettas have a pointier shape at their stomachs. Betta splendens can be up to 6.5 centimeters long.[2]
Breeding
The Siamese fighting fish has been bred to have large and colorful fins. Wild Betta splendens do not have bright colors. Bettas are a popular aquarium fish. They are known for their interesting behavior and ability to breathe air. A popular fin type is the veiltail, which has long droopy fins that look like a dress. Red and blue are the most common colors in betta fish. Some people think that white, black, and green bettas are rare. Before a male Betta splendens begins to mate with a female, the male betta will create a nest of bubbles by blowing mucus-coated bubbles towards the surface of the water.[4]
Behavior
If betta fish are kept in a small area, the males will fight each other. Bettas will also nip (bite) the fins of some fish. If a male betta engages with an opponent male, the betta will make his fins flare up, position his gill covers outwards, and move his tail in a lateral beating movement. They can also get aggressive if they see their own reflection.[4]

Rice paddies are believed to have been the first point of contact between bettas and humans.
