I do not own this fish, it was on show by another exhibitor at the fish show in Corby last year. It is a nice fish though.
I have had a london shubunkin in the past which had the proper standard body shape and fins. I have not seen another for sale since that matched the criteria so I still have a look in the shops when I go.
I tend to just have the common english goldfish, the ones that are not all that common. Tee Hee.
I do know of a breeder who specializes in show quality Bristols as well as the fancy goldfish. He is based in Birmingham. Must say though I have not been there for a number of years.
