I'm no expert at the different strains of bettas, but I don't think those are VT's. I might even go as far as to say that they are VTCT or mabey they have some plakat in them. I don't know, but I don't think thier VT's.
cant see much in the pic but if shes got 2 extended rays coming of one main ray but they dont seem very long then she could well be a Combtail (cross of CT and VT)and will hold the genetics of a CT
