10 gallon tanks? Fish?

I'm getting a ten gallon fish tank for christmas. I really want those bulging eyed goldfish, I'm pretty sure they are called black moor goldfish. I would like to have at least two of them, and any other kind of fish. What kind of fish can I put in there, and no I'm not going to get a goldfish that is going to grow really big, I just want as many small fish as possible. (: Thanks in advance.
