These are what we called "Butterfly-Tail"(obvious in the photos).
Actually, in the past, Chinese and Japanese keep goldfishes in a big clay bowl in the garden.
So, the goldfishes are viewed from the top of them but not from the side.
This is different from freshwater and marine fish keeping.
Unfortunately, it's impossible for the screensavers to be designed in the point of view from the TOP.
(If so, I have to place my monitor flat on my floor... HaHa...)
It lost so many nice chances to see the beautiful style of goldfishes~~~
