Same, my parents won't even think of a 20g. I do have a bad first fishtank, but it's my friends. It's a 5 and 1/2 gallon tank with 3 Platys and fry, and a cory. When she first got it it didn't have any thing in it, so I went with her to buy fish and plants. The next day she told me all of the Platys had died. Oh, and there were amano shrimp, but they died. So she got 2 more sets of 3 Platys and they all died. Finally, it came out! She wasn't using water conditioner! So now when I see her tank I want to cry, because the water is down 3 inches, it's cloudy, covered in algae, and there's no plants, only a rock and driftwood.
