The description of 73 Species Of Betta Fish (Ikan Laga / Cupang)

Betta /ˈbɛtə/ is a large genus of small, often colorful, freshwater ray-finned fishes in the gourami family (Osphronemidae). The best known Betta species is B. splendens, commonly known as the Siamese fighting fish.

All the Betta species are small fishes, but they vary considerably in size, ranging from under 2.5 cm (1 in) total length in B. chanoides to 12.5 cm (5 in) in the Akar betta (B. akarensis).

Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as rice paddies, slow-moving streams, drainage ditches, and large puddles.

The bettas exhibit two kinds spawning behaviour: some build bubble nests, such as B. splendens, while others are mouthbrooders, such as B. picta. The mouthbrooding species are sometimes called "pseudo bettas", and are sometimes speculated to have evolved from the nest-builders in an adaptation to their fast-moving stream habitats.

A phylogenetic study published in 2004 concluded tentatively that bubble-nesting was the ancestral condition in Betta, and that mouthbrooding has evolved on more than one occasion in the history of the genus. However it was unable to establish a correlation with any of three habitat variables studied: whether a species was found in lowland or highland streams, whether it was found in peat swamp forests, and whether it was found in water with fast or slow currents. Mouthbrooding species tend to exhibit less sexual dimorphism, perhaps because they do not need to defend a territory as the bubble-nesters do.

(Ikan Cupang atau Ikan laga adalah ikan air tawar yang hidup disungai-sungai kecil yang airnya mengalir lambat, dirawa-rawa atau pun digenangan-genangan air. Ikan yang sebagian besar spesiesnya memiliki karakter agresif dalam mempertahankan wilayahnya ini berasal dari negara-negara kawasan Asia tenggara, seperti Indonesia, Malaysia, Thailand, Vietnam dan Brunei. Warna dari ikan cupang bisa berubah dalam kondisi dan suasana hati tertentu.

Ikan yang memiliki panjang tubuh dewasa antara 2 sampai 12.5 cm "tergantung spesiesnya" ini memiliki 2 cara dalam berkembang biak. Sebagian spesies ikan cupang berkembang biak dengan cara menyimpan atau mengerami telur-telurnya didalam mulut induk jantan atau disebut Mouth breeder dan sebagian lagi berkembang biak dengan cara Bubble nest, yaitu dengan cara menempatkan telur-telurnya disarang busa "gelembung udara" yang dibuat induk jantan.)
