Comet Goldfish will generally eat all kinds of fresh, frozen, and flake foods. To keep a good balance give them a high quality flake food everyday. To care for your goldfish, feed brine shrimp (either live or frozen), blood worms, Daphnia, or tubifex worms as a treat. It is usually better to feed freeze-dried foods as opposed to live foods to avoid parasites and bacterial infections that could be present in live foods.
Comet Goldfish are some of the hardier species of goldfish. They are very undemanding of water quality and temperature. Many people try to keep goldfish in small one or two gallon bowls with no heater or filtration. But for the best success in keeping goldfish, provide them the same filtration, especially biological filtration, that other aquarium residents enjoy.

The shape and size of the aquarium is important and depends upon the number of fish you are going to keep. Goldfish need a lot of oxygen and produce a lot of waste.
- A large surface area of water will help minimize goldfish suffering from an oxygen shortage. Surface area is determined by the shape of the tank. For the same volume of water, an elongated tank offers more surface area (and oxygen) than a tall tank. In a fish bowl, filling the bowl to the middle offers more surface area (and oxygen) than filling the bowl to the top. Always provide the maximum amount of surface area.
- Providing a large amount of water per fish will help dilute the amount of waste and reduce the number of water changes needed.
- A general rule of thumb for young fish only is 1 inch of fish (2.54 cm) per 1 gallon of water. This rule applies only to young fish and is not adequate as they grow. Largergold fish consume much more oxygen than young fish so maintaining this formula for growing fish will stunt them, and can contribute to disease and even death.
- Keep the tank size and shape in mind when you are buying your fish. To allow for growth, either buy fewer fish than the maximum number of fish (based on the above formula) or be prepared to get a larger tank.
Use a gravel substrate and add some decorations that provide shelter for your pet goldfish. Driftwood and smooth rocks make good, safe decorations; and plants are especially appreciated, either live or plastic. A cover for the tank is desirable as it reduces evaporation and though they are not prone to jumping, on occasion somegold fish will jump out. Most aquariums come with a cover that includes lighting and will help if you have live plants.
Comet Goldfish can and do naturally change color, but color changes are also believed to be influenced by diet and the amount of light. Aquarists often report the reds and oranges of their goldfish changing to white. A fresh diet, along with good lighting but with shaded areas are suggested as the best way to maintain the original coloration, but are not always successful.
