Buy an aquarium with the greatest amount of surface area. This is where water meets the air. Goldfish would rather swim further (width wise) that deeper. A deeper tank means the water won’t be as well aerated
Goldfish can live for many years and reach their full potential if properly housed in a big enough tank.
It’s important to remember this equation: the smaller the quantity of water in the aquarium, the quicker it will evaporate. You’ll need to top up the water in a small tank regularly, especially in warmer weather.
Tank size and fish
When buying an aquarium take into account the number of fish that you want to keep as this directly affects the size needed.
Goldfish need a clean environment with plenty of room to grow. To the surprise of many people, a 10 to 20 gallon goldfish tank is really only sufficient for 1 goldfish.
Rule of thumb: adding another 10 gallons per fish is ideal.
It’s important to understand that small containers are suitable for a brief time only. Give your pet plenty of space to swim around.
Always use bigger receptacles to house healthy goldfish. Buy the biggest aquarium that you can afford.
Choosing the aquarium shape
There are shape options in patterns and forms available. For example tall, hexagonal, round, square…you get the picture.
These different shapes might be interesting, but by far rectangular aquarium is the most popular aquarium in use today. A rectangular shape is very practical and I like this shape because it gives a great frontal view.
Aquariums that are round provide an irregular view of your goldfish and tanks that are tall also have an unsatisfactory surface exterior.
Because of its capacity and proportions, the rectangular shape works well for the additional equipment you need: filters, pumps, decorations,etc. Good ventilation is provided with auxiliary or additional equipment and this makes the goldfish environment much more pleasant.
If you decide to buy a cheap aquarium, keep in mind they’re likely to be defaced when they’re cleaned and will turn yellow with time and use. They’ll also curve or arch more easily and you’ll have problems with the bigger ones if the materials used to make the aquarium are cheap.
What's the best material for a tank?
Glass is still the best choice because
- it gives good clarity
- it will last for many years
- is easily cleaned
Glass tanks are attractive and sturdy making them a great home for your goldfish.
An aquarium that’s made from all glass and is well sealed when manufactured should last a lifetime. Don’t take chances. Buy a tank made of good, strong material.
The right materials will make all the difference when it comes to housing your new little family members.
In the past aquariums were often made from synthetic compounds such as plexiglass. These inferior materials were used to keep cost low, but they scratched easily and became yellow with use. The acrylics available now are better quality but to purchase an aquarium that is of high quality they are more expensive.
Some people choose to house their goldfish in heavy metal-framed aquariums or goldfish bowls. These choices are often made because they’re not aware of better options.
- Goldfish bowls present problems such as overcrowding. The frontal view may suggest that a larger number of fish should be able to fit comfortably inside the bowl. In reality that could not be farther from the truth.
Metal-framed aquariums used to be associated with leaks due to rusting. This was a major problem but has been resolved thanks to modern silicone bondings and the production of frameless aquariums.
One of the benefits of metal-framed tanks is that they do protect the corners from being accidentally chipped. There are still various framed tanks on the market, but usually the frame is just viewed as being ornamental.
As the proud owner make it as enjoyable as you can for your fish. It’s gratifying if a little extra time is taken to choose the best possible place for them to live.
