How to Care for Carnival Goldfish

Carnival goldfish typically come home in plastic bags.

With proper care, a goldfish will live for 10 or more years. A well-treated goldfish can grow to several inches in length, too. Fish such as goldfish make enjoyable pets for busy people, because they don’t need much attention besides feedings and a clean tank. A fish you have won playing a carnival game may will require the same care that a goldfish from any other provider will need, as long as it's a healthy fish to begin with.

Buy a tank that allows your goldfish plenty of space to move and grow. While many people keep goldfish in small bowls, a 10- to 20-gallon tank is a better way to keep them healthy.

Check with a local pet store to see if the water in your area is fine for fish tanks. Water quality varies by location, and a local expert can help you determine if your water will work or if you need to buy filtered water.

Use a thermometer to check the temperature of the water in your fish tank. Goldfish do best if the water temperature is between 65 degrees F and 68 degrees F.

Find a good place for your fish tank. You want to make sure that your goldfish receive plenty of light and that the tank is in a safe and secure location, especially if you have other pets that might be curious about the fish.

Keep a hood or lid over your fish tank. This will keep dust and dirt out of the water, and prevent your fish from jumping out.

Feed your fish a packaged fish food that is designed for goldfish and follow the directions so you do not overfeed the fish. These foods will have the proper balance of nutrients to keep your fish healthy.

Change out some of the water in your goldfish tank every week. If you have a filter, change 10 to 15 percent of the water each week. If you do not have a filter, change 20 to 25 percent of the water.

Items you will need

  • 10 gallon to 20 gallon tank
  • Tank thermometer
  • Goldfish food
  • Aquarium hood

Tip

  • Keep the decorations in your fish tank simple. A few plants and some good gravel are all your goldfish really needs to feel at home.
