🐟 Half Sun Betta Fish (Betta splendens)
Solitary Display Fish • Halfmoon × Crowntail Cross • 180° Spread With a Light Fringed Edge
📋 The Half Sun Betta is a cross between the Halfmoon and Crowntail, combining the Halfmoon's full 180° tail spread with a lighter crown-like fringe along the edge. The ray extensions reach less than a third of the fin, noticeably shorter and softer than a true Crowntail's spikes.
Some sellers use "Half Sun" loosely to describe any fish combining halfmoon shape with crowntail traits, though the correct term for a fish showing full crowntail-level webbing reduction on a 180° spread is a Crowntail Halfmoon, a distinct combination. Half Sun bettas, like their Halfmoon and Crowntail parent lines, can show more pronounced territorial spirit than some other fin types, so keep it solitary. Males are territorial and males are territorial and must never be housed with another male.
