What Goldfish do I have and suggestions?

[dexsting]

We inherited a Goldfish and it seemed sad in it's little bowl so we bought a 20 gallon tank. But I'm curious what kind of goldfish he/she is?


I hope that image worked, if not I'll have to figure out another way to upload.

I figured knowing what kind of goldfish will help me figure out temperature settings and what other fish might be able to share the tank.

Thanks for any help!
