There are two groups of goldfish. While the first group is suitable for a tank, the other one is suitable for a pond. Goldfish suitable for the tank are generally shaped like egg and they will have double tail and bubble eyes. Examples of this type are moors, celestials, fantails, pompoms etc.The other species is suitable for a pond. These will require more space to move around. Examples of such species are commons, shubunkins and comets. If you try to put these varieties in the tank, they may not survive for a long time. What should be the size of the tank ideal for goldfish? You should try to get the tank as big as possible. If you are introducing a pair, you should have the tank capacity of at least 40 gallons. Generally 20 gallons of water per goldfish is considered ideal. However, when you transfer goldfish from a pond to the tank, you need to provide at least 60 gallons per goldfish to keep them happy.

They also grow large and very quickly! If you deliberately keep them in a small tank, they will be very uncomfortable and sometimes it will lead to problems which will lead to their death.

If you are providing appropriate environment and food then they can live up to 25 years!

Is it suitable to keep goldfish in a bowl? Absolutely not! One Goldfish needs at least 15 to 20 gallons of water with good filtration and maintenance. In the absence of such conditions, they will get suffocated. The bowl will not provide sufficient surface area also which will not provide enough oxygen for the fish.
