How much water does 6 goldfish need You will likely have been told that each goldfish needs 10 gallons (if you live in the US) but strangely enough only 20 litres (1 litre = 0.3 gallon) per fish if you live in Europe; alternatively you could have been told to calculate 5 litres for each cm of length of the fish, or consider 40 litres for the first goldfish but less for any additional fish.
How Much Water Does 6 Goldfish Need
Alone, they can live in a 10-gallon tank, but to be happy they need at least 20 gallons. And if you’re aiming for 3 or more goldfish (which is preferred), then 60 gallons is a safe size to opt for. For 6-8 goldfish, a 120 to 160-gallon tank is the optimum size.
How Many Goldfish Can You Have Per Gallon Of Water?
Use at Least Ten Gallons. A 10-gallon aquarium will be a fine starter size tank for two to four small goldfish, but the goldfish will not reach their proper adult size unless they are placed in a larger aquarium.

Do Goldfish Need Oxygen?
