Crowntail Betta
Betta splendens 'Crowntail'
Family: Osphronemidae
📍 Thailand & Cambodia
The Crowntail Betta features dramatically extended fin rays with webbing reduced to one-half or less of the ray length, creating the appearance of a spiky crown. This striking mutation originated in Jakarta in the 1990s and quickly became one of the most popular betta tail types. Males are bold and territorial; their long rays require careful attention to water quality and tank decor to prevent damage.
