Goldfish Tank & Aquariums

Choosing the right goldfish tanks and aquariums is a big decision for pet parents, as they play a vital role in ensuring the health and well-being of our treasured underwater friends. Some important factors to consider when purchasing goldfish tanks and aquariums are:

  • Glass or acrylic tanks: Both glass and acrylic goldfish tanks and aquariums are popular, with acrylic preferred because it's lightweight
  • Size: Goldfish are an active species, so it's advised to have a minimum of 20 gallons for your first goldfish, and an extra 10 gallons for each additional goldfish
  • Filtration system: Ensure your goldfish tanks and aquariums have a strong water filtration system, since goldfish produce a lot of waste
  • Substrate: Sand or other types of substrate are advised, because these are more stimulating for goldfish as opposed to bare-bottom tanks

Frequently Asked Questions about Goldfish Tank & Aquariums

What size tank do you need for a goldfish?

When it comes to the right size of goldfish tanks and aquariums, it's advised to ensure 20 gallons for the first fish and 10 gallons for each additional fish. Goldfish, in particular, need adequate room to swim and thrive.

What type of fish tanks are best for goldfish?

The best kinds of goldfish tanks and aquariums are ones with at 20–30 gallons of capacity per fish, with an additional 10 gallons for each additional fish. Additionally, goldfish tend to prefer squatter tanks as opposed to tall and narrow ones. Ensure your tank or aquarium includes a lid.

Is 2 gallons enough for one goldfish?

No, 2-gallon goldfish tanks and aquariums are not suitable for one goldfish. Unfortunately, in these conditions, a goldfish would suffer because they're an active species that need a lot of space to move around. It's advised to secure a 20-gallon tank per goldfish with an additional 10 gallons for each additional goldfish.

Can a goldfish live in a 5-gallon tank?

Unfortunately, a goldfish cannot live in a 5-gallon tank. It's advised to obtain a 20-gallon tank per goldfish with an additional 10 gallons for each additional goldfish.

How many goldfish should be kept together in a fish tank?

Goldfish are a social species and like to be kept in pairs or groups. Many recommend a 50-gallon tank or aquarium for up to three goldfish. The more room they have to swim around, the better. Goldfish are active and produce a lot of waste, therefore they need more tank room than other types of fish, especially in groups.

What are the best materials for a goldfish tank?

Ideally, goldfish tanks and aquariums should be made of glass or acrylic with a minimum capacity of 20 gallons per fish. A lid is also vital, as it prevents them from jumping out of the tank.
