Betta smaragdina, the emerald green betta, blue betta or Mekong fighting fish, Thai: ปลากัดเขียว or ปลากัดอีสาน is a species of betta fish native to Thailand and Laos, where they are found in the basins of the Mekong, Chao Phraya river mostly found at mun and Chi rivers in Isan region, Thailand. This species grows to a length of 7 cm (2.8 in). They get their green and blue colors due to refraction and interference of light that come from hexagonal crystals that are less than .3 to .5 miera.[2] This species is also found in the aquarium trade.[3]
