Betta splendens, commonly known as the Siamese Fighting Fish, is a species of freshwater fish native to Southeast Asia. Renowned for its vibrant colors and elaborate finnage, particularly in captive-bred males, it is a popular aquarium fish. Wild bettas typically exhibit duller coloration and shorter fins. Males are highly territorial and aggressive towards other males of the same species, hence the 'fighting fish' moniker. They are labyrinth fish, possessing a specialized organ (the labyrinth organ) that allows them to breathe atmospheric air, enabling them to survive in oxygen-depleted waters.

Tips Identifikasi
Fin Morphology (Males)
Captive male Betta splendens are easily identified by their exceptionally long, flowing, and often elaborate fins (dorsal, caudal, and anal fins). Wild males and females have much shorter fins.
Coloration
While wild bettas are drab, the intense and varied coloration of captive-bred individuals (red, blue, green, etc.) is a key identifier.
Labyrinth Organ
Observe the fish periodically surfacing to gulp air, indicating the presence of a labyrinth organ, a characteristic of the Anabantidae family.
Aggressive Behavior (Males)
Males will flare their gills and fins aggressively at reflections or other males, a distinctive territorial display.

- Sebaran geografis
- Native to the Mekong basin in Southeast Asia, specifically Thailand, Cambodia, Laos, and Vietnam. Introduced populations exist in other regions due to aquarium releases.

Fakta kunci
Labyrinth Organbehavior
Betta splendens possesses a labyrinth organ, a specialized respiratory organ that allows them to breathe atmospheric air directly from the surface. This adaptation enables them to survive in oxygen-poor waters.
Bubble Nestsbehavior
Male Betta splendens build elaborate bubble nests on the water surface to house their eggs and fry. They meticulously guard these nests and care for their offspring.
Aggressionbehavior
The 'fighting fish' moniker comes from the extreme territorial aggression males display towards each other, often fighting to the death if not separated. This behavior was historically exploited in organized fish fights.
Color and Fin Diversityamazing
Through selective breeding, Betta splendens has been developed into hundreds of varieties with an astonishing array of colors, patterns, and fin shapes, making them one of the most diverse ornamental fish species.
Lifespaninteresting
With proper care, Betta splendens can live for 2-5 years in captivity, though some individuals have been known to live longer.
