Description
The Emerald Green Betta is a wild Betta species known for its iridescent green and blue scales, particularly on the fins and operculum, over a brownish body. Native to the Mekong Basin, it is closely related to the Siamese Fighting Fish but is generally less aggressive. Males can still be territorial and should be housed carefully.
