What do you need to keep a goldfish alive?

- A tank: Goldfish need a spacious tank. The tank should be at least 20 gallons for a single goldfish, and larger for multiple goldfish.

- Water: Goldfish need clean, chlorine-free water. The water should be heated to the right temperature (72-78 degrees Fahrenheit).

- Food: Goldfish need to be fed a variety of foods, including flakes, pellets, and live food. Feed your goldfish only as much food as they can eat in about 2 minutes.

- Gravel: Gravel is used to line the bottom of the tank. The gravel should be small enough that the goldfish won't choke on it, but large enough that it won't get stuck in their gills.

- Plants: Plants can help to add oxygen to the water and provide shelter for the goldfish.

- Filter: A filter is essential for keeping the water clean. The filter should be running 24 hours a day.
