Ok, I just got my new fish, Sterling. She is a fair fish, and I think she is a comet. Not quite sure yet, but working on it. So my brother and I changed the water yesterday(his fish is in there too). We changed about half of the water...should we be changing more? Is there a difference between bowl and tank? Because we have them in a bowl right now...I know, bad, bad me. But we're going out tomorrow to buy an aquarium. So anyway, can you wonderful folks help me? I

Sterling a lot!
