"No one is a failure unless you try"
Recently I saw some calico telescope eyes at my LFS, and although I haven't wanted to own goldfish in YEARS, I absolutely love these guys. I was just wondering, would it be possible to keep one in a 10 gallon if I had an obscene amount of filtration going? I've heard the minimum tank size for goldfish is 20 gallons or so, but since this particular variety doesn't get anywhere near as large as a common, I figured one might be able to make an exception?
