The Betta Antuta (Betta antuta) is a large and spectacular wild Betta from the blackwater peat swamps of Borneo, Malaysia. One of the most impressive members of the unimaculata complex, it is a paternal mouthbrooder that can reach a substantial size, displaying a rich brown-olive body with vivid iridescent blue-green scaling and bold fin colouration. A commanding presence in any species aquarium, Betta antuta is a prized species for the serious wild Betta collector.
