Well, in looking at your website, Keith, I have to say that my white one with red spots is a Watonai, or maybe the Wakin if the tail is not long enough, which it is kind of in between the two as far as length right now. The reason I say this is that it does look like a common goldfish (longer tail though) from the side, but from above, it is definitely a fantail. The other two, Spot and Speck, with their big bellys, are fantails. They seem to have longer than normal tails, but maybe not as long as the ribbon tail ones. To be honest, I can't tell the difference between his fantails and ribbon tails. If you look at all of the pics under fantail, cover the description and try to figure which ones are ribbontail! I was wrong 50% of the time. LOL I'm happy to call them all fantail, though. But, that red spotted one is so unique the way it is marked and the fact it's body is nothing like the other two. From above, you see 3 red spots on it's tail, as it always has it spread out, plus the red spot on the dorsal fin and then red spot on the head. I just fell in love with that fish! I think I paid something like $5 for the 3 of them, different times, same place though.
I don't care for the downward tuck of the fantail, like the Jikin or Ranchu. I like the tails that look more "normal" and flow behind them.
