Petroleum, a fossil fuel, supplies more energy to the world today than any other source. The United States is the world's leading consumer of petroleum; in 1994, Americans used 7,587,000 barrels of oil per day.
Frequently test for ammonia and nitrite (you want both to measure zero). A pH test is also handy to ensure your goldfish's water is not too alkaline or acidic. This can be purchased at any pet store. Do not modify the fish's water, however, unless it is significantly different from neutral.
Try to keep the water at about 70 degrees. You will also need a filtering system to remove waste, which contains ammonia that is toxic to the fish. Buy the right home for the fish. If youâre a new goldfish owner, purchase a 2- to 5-gallon plastic aquarium kit with a filter, air pump, and chlorine remover. Release the fish carefully. Place the fish in its bag in the tank before releasing it to reduce stress. Take cover.
