Well yesterday i went to Petco to get some Koi and goldfish for this BIG urn/bowl thing outside. I originally planned on having the goldfish and koi together but the Petco rep said it was a bad idea, becuase of the possible diseases the goldfish might carry. And that I should keep them separate for a month or so. I had an empty 10 bought a filter and voila now I have an indoor tank setup. I also bought a air pump and 10" air bar. The tank looks great and they all seem to be doing well. I'm so happy I finally got a fish tank setup.
