If I understand correctly, its ok to keep a 12" fish in 6g of water

What people need to understand is that those rules are BS! It "might" work for a full grown small sized Tetra, but not other types of fish. heres a good example.. A foot long Oscar needs 100g of water to stay healthy, where a foot long Red Devil only needs 55g to stay healthy. They both come from the Cichlid family, but they each produce different amounts of waste, therefore requiring different tank sizes.

Another thing what people need to realize is that if you place a baby fish in a small tank when its young, BUT its still the proper size according to your " method, you are still stunting its growth. It need to be in the proper sized tank off the bat so it grows properly.

Thats why when you see most adult Oscars in pet stores, their bodies look all F'ed up. As in 1 side of the body sticks out further, their faces are just ICK looking (not talking about HITH) & they have messed up Jaws & sometimes messed up backs & eyes.
