What do you need to buy with a goldfish?

* A tank: Goldfish need a tank that is at least 20 gallons in size. The tank should have a lid to prevent the goldfish from jumping out.

* A filter: A filter is essential for removing waste from the tank water.

* A heater: Goldfish are cold-water fish, but they still need a heater to keep the water temperature between 65 and 75 degrees Fahrenheit.

* Gravel: Gravel provides a substrate for the goldfish to swim on and helps to keep the water clean.

* Decorations: Decorations can help to make the tank more appealing to the goldfish.

* Food: Goldfish need to be fed a high-quality diet of pellets or flakes.

* Water conditioner: Water conditioner helps to remove harmful chemicals from the tap water.

* Test kit: A test kit allows you to monitor the water quality and make sure that it is safe for the goldfish.
