There a lot of site share how to take care of goldfish, however the important point are: maintaining good water quality, comfortable temperature range, proper fish food, and following routine maintenance schedules.
Many goldfish types are very hardy, especially the Common Goldfish and the Comet Goldfish. These two are great for beginners. The Fantail Goldfish and Shubunkin Goldfish are also good beginner fish. Other hardier types include the Black Moor Goldfish and the Ryukin Goldfish. Once you’ve gained experience and confidence in keeping these hardier goldfish, try some of the more delicate, fancy goldfish like the Bubble-eye Goldfish, Celestial Goldfish, Oranda Goldfish, or Lionhead.
Make sure there is always no chlorine in your water tank. If there is chlorine, then you need to add de-chlorinator every time you add water to the tank. Chlorine can kill your goldfish. The chlorine can be checked with a chlorine test kit. The PH for your goldfish aquarium should be maintained between 7.2 and 7.6. You can get a pH testing kit from a local fish shop or most pet stores.
Ideal aquarium temperature for goldfish is between 65 ° – 68 ° F (18 ° – 20 ° C) but not higher than 72 ° F (22 ° C). Goldfish are cold water animals so do well in a cooler aquarium. Although goldfish is cold resistant, they do not do well with extreme temperature changes.
If you are in a house that becomes cool enough at night, you should check the temperature and stabilize it. You may have to add aquarium heater, as most models generally have a built-in thermostat to keep the temperature relatively constant. Goldfish can tolerate a gradual rise or fall in temperature.
If you keep goldfish in a pool of water outside, make sure the depth is more than 30 inches. In winter the goldfish will hibernate by the pool and be active again in the spring. It would be better if you plant the plants in the pond to help add oxygen to the pool water.
3. Goldfish Food
Goldfish are included in a group of omnivorous animals that eat anything. Most of goldfish are considered to be opportunistic eaters because they will eat the most and will not stop by themselves. Goldfish are different from most tropical fish, but they do not have stomachs. Because of this, they will produce excessive waste when eating too much.
There are a variety of goldfish food products available: pellets, flakes, and even live foods such as brine shrimp. The rule of thumb is to feed your carp several times a day but no more than they can consume within 5 minutes. If overfed, the goldfish will overeat and produce excess dirt, which will cause the tank to become dirty and the pH rises. It’s not healthy for fish. Goldfish does eat live plants, so choose plants for a goldfish tolerant aquarium.

Weekly water changes of 25-30% are recommended. Snails can be added as they reduce the algae in the tank, helping to keep the aquarium clean.
