Crowntails are a type of “fringe-finned” domestic betta having fin rays that extend significantly beyond the webbed portion of the fins. The supporting webbing around the fin rays is reduced and the rays protrude past the edges of the fin membrane. The result is a scalloped appearance or the appearance of hyper-extended rays as seen in Crowntails where the webbing is substantially reduced.Cross Ray – In the schematic, this is manifested by pairs of primary rays which curve over each other.
