Hello everyone,

I need some advice. I'm new to the hobby. Last Halloween my kids got two comet goldfish. Now, we have a 10 gal. tank and I want to add more fish. I've heard other goldfish are best, but I was wondering what other types of fish, besides goldfish, would work? I'm wanting variety and to make the tank more colorful. Thank you for the help.

Without a heating and filtration system u don't have much of a variety
