Origin/Distribution:
Bettas originate in the shallow waters of Thailand (formerly called Siam, hence their name), Indonesia, Malaysia, Vietnam, and parts of China. These areas are home to acres of rice paddies, ponds, slow moving streams and swamps, all of which are home to Bettas. Today Bettas have been introduced in many locations, giving rise to non-native populations in a number of countries.

As demand has grown for Bettas, they have been captive-bred globally, both commercially and by private individuals. Virtually all species for sale are captive-bred. Betta splendens is easily the most popular species of Betta bred and sold in the aquarium trade. These captive bred species have become significantly different than the original wild caught specimens they are derived from, having been bred to bring out specific features such as new varieties of tail and fin types as well as unique colors.

The common name, Siamese Fighting Fish, was coined due to the practice of organized fights between males, much like cock fights. These matches continue to this day, driven by the income from betting. In some locations males are bred specifically for aggression, to ensure better fights. The brilliant coloration, and long flowing fins of the Betta make it one of the most well known of aquarium fish. Colors range from red to blue to white. Females are not as highly colored, and have much shorter fins.
Description:
The brilliant coloration, and long flowing fins of the male Betta make it one of the most well known of aquarium fish. Females are usually not as highly colored, and have much shorter fins. In nature, this species is not usually brightly colored. However, captive breeding programs have resulted in a wide variety of colors, including white, yellow, orange, red, pink, blue, green, turquoise, brown and black. A myriad of combinations are seen, from solid color to those with different fin and body colors, to patterned colors.

Fin types have also changed due to selective breeding. Veil tails have been joined by Crowntails, Deltas, Fans, Halfmoons, Lyre and Split tails, to name a few. Betta competitions and breeding to compete in competitive shows, brings new variations to the market regularly.

Both sexes have a torpedo-shaped body and an upturned mouth geared for eating at the surface. Mature adults reach a size of two to three inches, with females being slightly smaller than the males. A unique feature of this species is the presence of a labyrinth organ that allows them to take oxygen from the atmosphere instead of from water, thus allowing them to survive in low-oxygen waters.
Tankmates:
Males cannot be kept with together, unless there are separators in the tank. Multiple females can generally be kept together without problems, and a single male can also be added to the mix. They can be kept with other peaceful species of fish, as long as they are small and are not fin-nipping types, such as Tiger Barbs. Male Bettas should not be kept with other fish that have similar body types and long fins, as they could mistake them for rivals.
Habitat/Care:
Bettas are one of the most recognized, most colorful, and often most controversial fish in the freshwater hobby. Debates rage about the appropriateness of keeping them in small bowls. To fully understand their needs it is important to become familiar with their native habitat, where they live in large rice paddies, shallow ponds, and even in some slow moving streams. Although many fish keepers are aware that Bettas come from shallow waters, what is often overlooked is the water temperature.

The home countries of the Betta are tropical, which means the water temperature is quite warm, often into the 80's. Bettas thrive on heat, and will become increasingly listless when the water temperature falls below 75 degrees F. Water temperature is perhaps the biggest argument against keeping a betta in a tiny bowl, which cannot readily be heat controlled.

Even though Bettas do well in waters low in dissolved oxygen, that does not mean they require less oxygen than other fish. Bettas have a special respiratory organ that allows them to breath air directly from the surface. In fact they inherently must do so. In experiments where the labyrinth organ was removed, the fish died from suffocation even though the water was saturated with oxygen. For this reason, Bettas must have access to the water surface to breath air directly from the atmosphere.

Optimally the water for keeping healthy Bettas should be soft, warm, with a neutral to slightly acidic pH. Water movement should be kept to a minimum, which means that power filters and powerheads are not suitable. Bettas may be kept in a community tank as long as the water conditions are met, and if no aggressive or fin-nipping fish are present. However, only one male may be kept in each aquarium, unless they are separated by a barrier.

The use of plastic boxes that hang inside the aquarium are a suitable option for keeping more than one betta in a tank, or for keeping them in a tank with fish that might nip their fins. Females will generally not fight with each other, and may be kept in the same tank.

NOTE: Selling a Betta in a vase with a plant has become a popular sales technique. However, a flower vase is not a suitable environment for the betta. For more information read, "Is it Safe to Keep a Betta in a Vase?".
Diet:
In nature Bettas subsist almost exclusively on insects and insect larvae. They are built with an upturned mouth that is well suited to snatching any hapless insect that might fall into the water. Internally their digestive system is geared for meat, having a much shorter alimentary track than vegetarian fish. For this reason, live foods are the ideal diet for the betta, however they will adapt to eating flake foods and frozen and freeze dried foods.

Brine shrimp, Daphnia, plankton, tubifex, glassworms, and beef heart, are all excellent options that may be found frozen or freeze dried. If flake food is fed, it should be supplemented with frozen and freeze-dried foods, and if possible live foods.
