How to Set Up a Proper Goldfish Aquarium

How to Set Up a Proper Goldfish Aquarium

Goldfish are wonderful first pets for children. Their brilliant color and extremely personable expression and behavior captures the hearts of young aquarists and the young at heart.

Goldfish are the most popular home aquarium fish, but how to properly care for them is not very well understood. Who has not heard stories about parents carefully replacing one goldfish after another and hiding the fact that their cherished "Goldie" is actually "Goldie No. 3?" While the intention may be well meant, this act perpetuates many myths and improper goldfish care.

Should Goldfish be kept in bowls?

Goldfish are commonly kept in very small containers without filtration or heaters. This less-than-ideal living condition is the number one cause of goldfish loss. Goldfish develop at a rapid rate and quickly outgrow these containers. A Goldfish that is a few inches long can get as large as 6 inches or even a foot, depending on the breed. Goldfish require lots of room and a 28-gallon aquarium is about right for one ornamental Goldfish. If you want to keep more than one, you are going to need at least 10 additional gallons per adult fish. Due to their size, Goldfish tend to produce more waste, which in turn affects water quality. Without proper filtration and regular water changes, visible and invisible waste materials build up to create a toxic environment. Combined with fluctuating water temperatures, it is no wonder most Goldfish are replaced frequently and are considered difficult to keep.

How long do Goldfish live?

Goldfish that are properly housed and cared for are extremely long lived. A beautiful Goldfish set up can provide many years of enjoyment and nurture values such as responsibility, compassion, and a lifetime love of pets. Invest in a proper Goldfish aquarium setup for your child's future.

A proper setup should consider the mature size of the Goldfish and provide ample swimming room. Good filtration and a heater are necessary to maintain stable water temperature as well as healthy and clean aquarium water. Other basic essentials include a thermometer, a test kit, and a water conditioner. We've compiled a list of essential aquarium equipment for a 29-gallon goldfish aquarium. All you need to supply is the aquarium, decorations, and the creativity to create a successful Goldfish haven.

Question :

Can I keep different breeds of goldfish in the same aquarium?

Anwser :

Housing different breeds of goldfish is fine. However, it is best to separate goldfish with different swimming habits. Active goldfish such as Shubunkins or Comets can stress slower swimming Fancy (ornamental) or vision-impaired varieties.
