Beautiful Betta Fish

Beautiful Betta 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 various bettas can be divided into two groups, based on their spawning behaviour: some build bubble nests, such as B. splendens, while others are mouthbrooders, such as B. picta.
