Help identifying fish

[HannahJo]

I need help identifying this fish. It came from my coworkers koi pond. He said its a shubunkin but I have doubts...

Here is something to start with - there are different body shapes!

Aren't all shubunkins calico? If not it may be a London shubunkin, they are more stout than the other types.

It´s a sarasa. One of the varieties of the standard goldfish.
I´ve kept sarasas as well among my koi.

Lost the other link I had...oops.

Like I´ve already mentioned this is a sarasa. Just like the shubunkin it´s a variety of a goldfish. That´s the only link between these two varieties.
