The Blue betta (Betta smaragdina) is a freshwater fish of the family Osphronemidae that grows up to 7 cm.
Description
The emerald betta is a small labyrinth fish from fresh water of Thailand and Laos. The species grows to about 7 cm; males gleam emerald-green with rows of glittering scales on a dark body, while females are plainer. As a labyrinth fish it can gulp air at the surface with a special breathing organ and so survive oxygen-poor water. The male builds a bubble nest and guards the eggs. It feeds on small insects and invertebrates. The fish is popular in the aquarium hobby. The IUCN assesses the species as Least Concern (LC).
