Halfmoon Betta
Betta splendens 'Halfmoon'
Family: Osphronemidae
📍 Thailand & Cambodia
The Halfmoon Betta is one of the most recognisable and popular betta cultivars, characterised by the spectacular 180-degree spread of the caudal fin that forms a perfect half-circle when fully flared. Selective breeding has produced individuals with extraordinary fin size and vivid coloration in virtually every hue. The large fins require pristine water quality to prevent fin rot and tearing.
