How Do You Take Care Of A Goldfish? (Beginners Guide)

Every aquarist has maintained a goldfish at some time. A goldfish in a bowl may have been a prize at the local carnival, a birthday party gift, or even a Mother’s Day gift for most people. This month, I’d like to take a quick look at goldfish husbandry and care.


Goldfish are members of the Cyprindae family of fish. This distinction is shared by many thousands of other species, including Barbs, Red Tail Sharks, Rasboras, and others. Carassius auratus is the scientific name for goldfish. Carassius refers to various members of the Carp family, while auratus literally means “overlaid with gold.” Goldfish, together with Koi and pond carp, make up a significant percentage of this species.

Goldfish come in a variety of forms and sizes. The ‘common’ goldfish looks more like the several varieties of carp found in ponds and lakes across the globe. Goldfish originated in temperate Asia but have since spread around the globe.

Domestication History

As early as 1300 years ago, several societies started to ‘domesticate’ goldfish. They chose genetic features including color, fin form, and body shape. As a consequence of this careful breeding, we now have a plethora of goldfish kinds accessible to us as hobbyists. The common goldfish, which is also marketed as a feeder fish in many pet shops, resembles its wild natural great-grandpa in Asia. However, all of the fancy varieties, such as veil-tails, bubble-eyes, orandas, and so on, are all strains generated by selective breeding and do not exist naturally in that form.

Preferred Water Temperature

Goldfish can survive a broad variety of temperatures since they are temperate creatures. When the water at the surface of a natural pond or a big enough water garden freezes, goldfish may even winter over. In the tank, keep the temperature between 68 and 76 degrees Fahrenheit. Cooler water is preferable for their survival due to metabolic needs.

Are Goldfish Dirty?

Goldfish are pigs that are born naturally. They’re a shambles. They also eat a much. As a result, many goldfish keepers face the most difficult challenge: poor water quality. Goldfish, like other fish, love to live in clean water. They can handle a broad variety of pH levels, but prefer water that is neutral to slightly basic. They do not thrive in any aquarium that contains ammonia or nitrite. They should be maintained in well-filtered aquariums since they may readily create large amounts of waste and ammonia. Yes, filtered aquariums are available. The problem is that most individuals start with a tiny dish.

Is Goldfish Easy To Keep?

Unfortunately, for many people, their first encounter with fish in general is a negative one. A goldfish in a one-gallon dish is a formula for catastrophe. They eat a lot, as I already said. They also generate a lot of garbage. As a result, they will collect extraordinarily high concentrations of the substances that are most hazardous to them in this little container. You could change the water every day, but this might be stressful for the fish. As a result, it’s recommended to keep the goldfish in a filtered aquarium.

Goldfish Compatibility With Other Fish

Because goldfish are so dirty and grow so enormous, it’s advisable to keep just one tiny fish every ten gallons. As they grow in size, each fish might potentially take up thirty gallons! This, along with their tendency to dig about the gravel and destroy plants and rock work, as well as their preference for colder temps, makes them less than ideal for the community aquarium. Goldfish are generally calm fish that get along well with a variety of other species, but they have different requirements than most other fish and would most likely never flourish in a communal aquarium.

Best Diet For Goldfish

The last issue I’d like to mention is feeding and nourishment. Goldfish in the wild are opportunists. This vegetation-loving fish has evolved into an opportunistic eater over many thousands of years. As a result, whenever a goldfish is presented with food, its innate impulse is to consume it.

Most foods on the market today have a high protein content. This is considerably different from their natural diet, which is high in fiber. In the wild, they mostly consume algae, grasses, and water plants. As a result, we must be cautious about how much ‘high protein’ food they eat in our tanks.


Overfeeding is another underlying issue. As previously said, goldfish will always eat when given food. This, of course, is their undoing, since they constantly seem hungry. Too many aquarists have cruelly murdered their goldfish in order to satisfy that insatiable thirst. Unfortunately, the fish has a good chance of eating itself to death.

To actually rip its intestines, or to cause a digesting backlog that leads to death. So the simple method is to monitor feeding. Once a day, I suggest one to two pellets for each fish. This may seem harsh but bear in mind that these fish dwell in a tiny area. There are no predators awaiting them, and no currents to contend with. Their water quality should be consistent (we hope), and they have nothing to do. As a result, their calorie requirements are quite low. And one to two pellets will be enough for them to thrive and live in your aquarium.

Goldfish Lifespan

Goldfish are lovely pets but bear in mind that their needs vary drastically from what a bowl can give. Many individuals have kept goldfish for many years. They may easily survive into their twenties, with some premium goldfish living twice as long. So, the next time you decide to get an adorable little goldfish, think about how long it will be in your life and its eventual size, and build up a gorgeous goldfish tank!
