It is with thanks to Dr. Joanne Norton that us angel fish breeders can produce all to colour, fin and scale varities that we produce today.
There are more colour forms that Dr Norton does not list, but most of these are colour varaitions of standard genes, ie the blue Kio that I am currently producing are just a colour varaition of standard Kio, that I have fixed to remove the gold cap and have a more blue sheen to the white body.
