When the CHENMASWIL team was developing the modern halfmoon in the 90s, it was Jeff Wilson who bred the first "mutants". These fish appeared from a cross of his lines with those of Laurent Chenot [1]. Because of their parthership the team regularly exchanged fishes for their HM breeding program they all became familiar with this mutation. Initially they were fascinated by these fish but they appeared to be weaker than the normal fish from the same spawn and failed to spawn. Because of these problems and the fact that they were now producing normal halfmoons of good quality they finally lost interest in these fish. The mutants were never used in their breeding program to develop the halfmoon. Jeff Wilson and Pete Goettner presented some of these fish at the IBC convention around 1993/1994. At this time they described these "mutants" as blonde diamond halfmoons referring to the phenotype of the fish, they were always blonde (pale color) and when not flaring their caudals had the shape of a diamond.

Lors de la création du type Halfmoon, c'est Jeff Wilson qui a élevé les tout premieres "mutants" de type Rosetail.
A cause de tous les problèmes inhérents à la forme Rosetail extrême, ces Bettas n'ont jamais été utilisés dans les programmes de reproduction de l'équipe "Chenmaswil" (Laurent Chenot, Rajiv Masillamoni, Jeff Wilson).

Les "mutants" (Rosetails extrêmes) étaient toujours de couleur pâle, et porteurs de gènes pour blond.
