Apart from the common goldfish that we are accustomed to seeing in films, photos, and cartoons, they have other breeds that are commonly termed as “fancy goldfish”: Oranda, Ranchu, Comet, Fantail, Ryukin are very popular breeds of Goldfish. They range from orange-gold to greyish white with golden spots, some have black spots, silvery-white with gold swashes and are even olive green.

They also range in sizes. Expanding from 6 inches to even 2 feet long at 10 pounds, goldfish grow according to the environment around them.

But they require special care too. Goldfish prefer a 68°F to 74°F temperature while Comets and Shubukins prefer 60°F to 70°F. The rapid change in temperature, pH, and other factors leads to drastic health changes in Goldfish. Hence, they require constant parameters. They are also quite sensitive to even small levels of Ammonia and Nitrite. They also do not like to share their space with every kind of fish. They are foraging, bottom-feeding fish and can be quiet aggressive with other tank mates.

The greatest thing about Goldfish is they grow into their environment. If you have healthy water and optimal living conditions they live a long and healthy life growing massive in size.

All these factors make the goldfish that special yet not so uncommon fish to be kept as pets in our aquariums.

Filters

Goldfish make a mess like there is no tomorrow. The goldfish eat a lot and they also excrete a lot of waste products. Hence, a filtration unit is one of the most important things to have in your aquarium kit. The filtration unit filters out the waste products which is ammonia, nitrates, and nitrates away from the water in the tank and saves the goldfish which is quite sensitive to ammonia levels from catching different kinds of diseases.

Lights

Lights are not just decorative pieces in your aquarium. Lights and darkness provide the fish with the opportunity to set up natural sleep patterns. Goldfish and their feeding habit are also affected by light patterns. There are a lot of studies that show the lack of light leads to the lack of vitamin D which causes a lot of diseases in goldfish like discoloration.

Heaters

The main use of having a heater in an aquarium is not to heat the water to a certain temperature but to maintain the temperature at a certain level. The goldfish react very badly to drastically fluctuating temperatures and hence a heater is needed to maintain a constant temperature.

Substrate

The substrate is the base of your aquarium. Traditionally you have three kinds of substrate options in gravel, sand, empty tank. Goldfish are bottom-feeding fish and they like to forage and move around quite a lot. Hence the substrate should be selected in a way that does not disturb and pollute the water and also does not get stuck inside the mouth and the gills of the goldfish.

FAQs

How much water does a goldfish need?

The answer to this is: the more the better. Goldfish are special fish in the sense that they grow into their environment. The environment dictates how big the goldfish becomes. So, a goldfish that lives in the pond will obviously be healthier and larger than a goldfish that lives in a fishbowl. Hence if you want your goldfish to be properly sized you need a minimum of 30 to 50 gallons of a tank and that measures a minimum of four feet in length.

If you plan to add one more goldfish in it, add an additional of 12 gallons of water per goldfish added.

How do I set up my tank?

  • Install a filtration unit. Choose a filter with a high flow rate. The flow rate is measured in gallons per hour. Say you have a 20-gallon tank, you need a filter that has a flow rate of at least five times that volume.
  • Do not use under gravel filters for a goldfish tank since they disturb the water substrate and pollute the water. We urge you to use a canister filter instead.
  • Add a suitable size of gravel substrate. Do not turn the filter on just yet. Put in gravel as a substrate but make sure the gravel is sized properly so that the goldfish do not nibble them in or that the gravel does not get stuck in their mouth.
  • After doing this it is the time to add decorations if you want them in your tank. Add a rock, plants, or anything else you want to put in at the bottom of your tank.
  • Now is the time to add the water. Make sure you only fill the tank to halfway and then add dechlorinated water if you are using tap water. Stop at half full and adjust your decorations then fill the tank with clean, cold, treated water all the way to the top and make sure you leave an inch or so of space at the top.
  • After doing all this, now is the time to turn the filter pump on. Allow the water to cycle for several minutes so that it becomes well circulated and only after that add goldfish.
  • Do not forget to check the temperature before adding your goldfish to make sure the temperature is between 70°F to 70°F.
  • Last but not the least, make sure everything is working properly and there are no leakages.

How do I take care of my goldfish and tank?

Make and implement a maintenance schedule for cleaning up your goldfish aquarium. Then add a few things you need to do daily and a few things that you need to do on a much larger time span.

  • You need to feed your goldfish daily and you should not just depend upon packaged food but also mix live and frozen food along with plant elements.
  • You should check your goldfish for any kinds of unnecessary spots or stress symptoms.
  • Do not depend upon the thermometer that the water heater present already in the aquarium kit has. Check the temperature of the water by yourself.
  • If there are any visible large particles get rid of them.
  • Clean your substrate on a weekly basis by using this siphon.
  • Replace 25% of the water on a weekly basis.
  • If there any green tinge in your water you need to eliminate the algae accumulation.
  • Examine if everything is working properly and wipe the exterior as well as the interior surface.
  • Examine the water for nitrates, nitrites and ammonia and pH level by using aquarium test kits.
  • Replace the filter as per the manufacturer’s guidelines.
