Is there anything special about this breed?

From what I can tell, (Just did some web-searching) it is a intermediate between a Wakin and a Ryukin. I suppose they are extremely hard to find, and I only found one picture of them by doing a google image search "Watonai Goldfish".

alot of times the goldfish will get called a mix cause they have traits of 2 fish in one, like a dragon eye Oranda. Means an Oranda with telescope eyes

Wow thats neat.I bet there beautiful.

There's a nice pic of watonai here. Scroll down to pic #6

My new goldy looks a bit like them.
