Common goldfish are among the largest species of fish that can grow up to 18 inches long compared to other specially bred goldfish. A goldfish can live comfortable in a 20 gallons of water tank alone, or in 30 plus gallons of water with a tank mate. However, experts recommend a 40 to 55 gallons of water tank for two goldfish.
Goldfish require a consistent water temperature. It is important to choose water filters that do not heat up the water. In addition, place your aquarium away from light, or places where the aquarium is most likely to receive heat from the outside.
