Can a Goldfish Live in a 5 Gallon Tank? (Here Are the Details)

While some believe that it’s impossible to keep a goldfish alive in a 5-gallon tank. But how much space do goldfish need? Can they survive in a 5-gallon tank? Read on to find out!
Yes, a goldfish can live in a 5-gallon tank. However, it is important to understand that this size of tank does not provide enough space for the fish to grow properly and requires frequent water changes since it is more prone to rapid water pollution. So my opinion is at least a 20-gallon tank should be for goldfish.
In this article, I’ll discuss what types of goldfish can survive in a 5-gallon tank, the size of the goldfish, and any other considerations you should keep in mind when setting up your aquarium.
Size of the Tank According to the Type of Goldfish
| Goldfish Type | Tank Size (Gallon) |
| Comet Goldfish | 10 to 15 gallons for 1 goldfish |
| Shubunkin Goldfish | 15 to 20 gallons for 1 goldfish |
| Common (fancy) Goldfish | 20 to 30 gallons for 1 goldfish |
| Telescope Eye Goldfish | 20 to 25 gallons for 1 goldfish |
| Bubble Eye Goldfish | 15 to 20 gallons for 1 goldfish |
An idea is available from the table above, goldfish of different types require different tank sizes. For example, comet goldfish need a minimum 10-gallon tank while bubble eye goldfish should be provided with at least a 15-gallon tank.

Will a Goldfish Be Happy in a 5-gallon Tank?
The debate about whether or not a goldfish can survive and be happy in a 5-gallon tank has been ongoing for many years now.
Aquarium enthusiasts have argued this point, with some stating that it is impossible to keep one alive in such small conditions while others say they can thrive happily.
To answer this question, it is important to consider the size of the goldfish, the type of goldfish, and any other considerations that need to be taken into account.
In terms of size, most aquarium experts agree that a single adult goldfish should have at least 10 gallons of tank space. This means that a 5-gallon tank simply won’t provide enough space for a single fish to grow and thrive.
On the other hand, you may be able to keep two or three goldfish in a 5-gallon tank as long as they are not overly large or active.

How Often Do You Need to Change the Water in a 5-gallon Tank?
Since 5-gallon tanks are so much smaller than larger aquariums, they require frequent water changes.
This is because the amount of waste produced by a goldfish in such a small tank can quickly build up, creating an unhealthy environment for your fish.
As a general rule of thumb, you should aim to do at least one partial water change (around 25-50%) per week in a 5-gallon tank.
Additionally, it is important to keep up with regular maintenance tasks such as cleaning the filter, gravel vacuuming, and changing out any decorations that become covered in debris.
