It is a VT. Comb has nothing to do with the tail type, but just a trait that any tail can carry. I don't see this fish having much "comb" . It looks to me like most of the caudal was damaged and healed like it is.
if you look closer, you can tell that it's a little comb coming out but from far distances it's a reg- veil tail. To me it's a comb but however who think it is cause i don't care. Its all siamese fish anyways. A halfmoon is genetic froma rt,ct,pt,vt,dt anyways so it's all bettas.
