The Goldfish is a favorite fish for many. How many of us didn't keep them at one time or another? Goldfish are usually very hardy fish and they can live in temperatures ranging from 40°F - 90°F (4°C - 32°C). It is important to note that this fish has an extremely long lifespan if cared for properly, so getting one can become a long term commitment. Many varieties of this fish are available with many different markings, fancy varieties and colors including gold, orange, white and black.
They can sometimes come down with swim bladder disease and occasionally freshwater ich. It's very important to provide your fish with frequent water changes and quality, nutritious fish food.

To increase your chance of success with keeping them, try not to keep them in a tiny bowl. A tiny bowl will become polluted quickly and you'll have to perform maintenance all of the time. Instead get your goldfish at least a 20 gallon tank with a good power filter or canister filter. Also, if you want to keep multiples, try for a minimum of 10 gallons per goldfish after the initial 20 gallons for better long term success with this fish.

Goldfish Care Summary
Allow adequate volumes of water, preferably 20 gallons for one and 10 gallons (38 liters) per additional goldfish.
Perform frequent partial water changes and gravel vacuuming while avoiding wide water quality fluctuations such as temperature, pH, etc.
Avoid keeping them in small goldfish bowls. Most bowls are simply inadequate to properly care for a fish. They only hold a gallon or two, need frequent cleaning, it's hard to use a filter, and provide little to no swimming space for your fish. What a miserable existence this has to be. A better option would be to place them in a large species only goldfish aquarium.
Give your fish a high quality and varied diet. Don't get the bulk size containers since fish food does lose nutritional value as it ages and as the top of the container is opened and closed every day. Think really stale potato chips. It's better to buy your fish food in smaller containers in this case.
Learn about the aquarium nitrogen cycle if you don't know about it already.
Don't over clean the filter! Rinse out the filter media in discarded aquarium water and re-use or only replace half the filter media at a time to avoid losing most of the beneficial bacteria needed to keep the water safe for your fish.
Remember that the Goldfish will grow in size and that they can live for quite a long time if cared for properly.

Care Level : Common varieties are easy and good for the freshwater aquarium fish beginner who is willing to perform the frequent water changes required in smaller setups. Some of the fancy varieties can be slightly more difficult to care for and need more stable water conditions and high quality foods. See the summary above.

pH : 6 - 7.5

Temperature : 40°F - 80°F (5°C - 27°C)

Lifespan : 10 - 30 years

Origin / Habitat : China originally, then Japan, Asia and the rest of the world.

Temperament / Behavior : Very peaceful

Breeding Goldfish / Mating / Reproduction : Not very common in home aquariums but you can try. Make sure you are ready to deal with the babies before you start your breeding program. Give them a water temperature between 75°F and 80°F. Get them ready by feeding fish food high in protein and make sure that they have good water quality. When they are ready, they will lay their eggs on vegatation on the bottom of the tank. You will have to remove the adult fish to prevent them from eating the eggs which usually hatch within 7 days. Prepare your fry foods such as infusoria and brine shrimp and have it ready in time to feed the baby goldfish.

Minimum Tank Size : Preferrably a 20 gallon or larger and 10 gallons for each additional goldfish if kept in groups.

Compatible Tank Mates : Usually do better when kept with other goldfish. Other potential tank mates include white cloud mountian minnows and similar cold water species. Watch closely if you introduce different species to your tank though and be prepared to remove them if it's not working out.

Disease / Illness :  Unfortunately, they can be quite susceptible to swimbladder problems due to the various types or varieties that have been produced over the years. Ich or white spot disease and fungus problems are also frequently encountered.

Fish Food / Diet : Will gladly accept most fish foods, including flakes, live and freeze dried varieties. There are foods made specifically for goldfish. They are omnivorous, which means that they will eat foods of plant or animal origin.

Tank Region : All over the tank

Gender : Males may have small white spots called tubercles around their gill areas when ready to spawn. Females may be noticeably larger when swelling with eggs and the males may start to chase the females around the tank.

Similar Species : Cyprinids

      This means your fish are already full and are just playing with food or they might not like the food (try different types of food as well e.g. flakes, pellets etc) fish only eat 2% of their body weight in a day so don't over feed them as the extra food will settle down it will create bacteria.

      you should only put enough food which your fish eat in a couple of minutes after that remove the remaining food. you can estimate the amount of food your fish eat and start feeding accordingly.

      hope this helps, also please share your fish photos in the gallery.
