How To Choose The Best Goldfish Tank?
What Is The Ideal Size Of A Goldfish Tank?
You think that a small goldfish tank is the most suitable choice for your small fishes, right? Let me remind you that goldfish grow quickly and they can live for a long time. Thus, it's better to buy a large tank from the beginning. You don't have to upgrade the tank when your goldfish reach adulthood size.
If you own one-two goldfish, I strongly recommend you choose a 20-gallon tank. Meanwhile, you should invest in a more than 50-60-gallon tank for a school of fish.
Here are other reasons to pick up a large tank:
It requires less maintenance, fewer water changes, but you can keep this tank clean and clear easily. Fewer changes of water not only help you save a lot of time and effort on your part but also give your goldfish benefits. This type of fish is sensitive to temperature, so changing the water regularly can be stressful.
The tank size can influence your fish body's growth. A small tank inhibits this development, so your fishes can't reach a proper size. On the contrary, a large goldfish tank gives your fishes an unrestricted space so that they can grow up to 10 inches long.
The goldfish can live up to 20 years in the right conditions. But, if you inhibit their growth in a small tank, they just can live a few years.
As I mentioned, goldfish grow quickly, being bigger and heavier in a short period, so they require more oxygen. You need to provide your fishes with a large tank for their well-being, having plenty of surface area.
The more significant goldfish are, the more waste they make. A large tank containing more water volume can dilute the waster. So, the water quality is slowly influenced compared to using a small tank.
Space available plays a vital role in choosing a goldfish tank. If your office is small or you have a limited apartment, it's hard to set up a large goldfish inside.
What Is The Perfect Shape For Goldfish?
Goldfish needs surface area instead of depth because they enjoy swimming the tank's length, so you had better choose a rectangular tank.
Which Material Do You Need?
The majority of goldfish are made from glass or acrylic. Each of them brings specific benefits and drawbacks, so your choice will depend on your needs:
Acrylic
This is a perfect choice for people who want to transport and move their goldfish tank regularly because this material is lightweight and easy-to-lift.
If your family has children or own dogs and cats, selecting acrylic is better than glass material because it can deal with small collisions and impacts without breaking and cracking.
Another plus point is the acrylic tank's bonding process, which is so good that the seams are invisible without leaking over time.
Moreover, the acrylic retains heat better than another material, which leads to less extreme temperature fluctuations.
Glass
Although glass tanks won't be scratched, it's straightforward to crack and break. They can keep their original shape over time, but this is a challenging task for acrylic material. After unboxing an acrylic tank, you will see a stunning look. However, the model will yellow or get cloudy more or less if you let it expose to direct sunlight too much. The glass material won't cloud and discolor no matter how long you use it under the sun.
This material is heavy. So, if you choose a glass 200-gallon tank, it is challenging to lift and move.
The glass material just comes in rectangular tanks, but this is the best-suited shape for goldfish.
Which equipment do you need in your goldfish tank?
Filter
Most goldfish tanks available on the market have this filter that takes responsibility for removing your fishes' mess and waste, toxins, and other buildups. This part is essential, so you should choose a highly-efficient and high-quality filter system.
Lights
Though goldfish don't need plenty of light, your plants in the tank require an amount of lighting. Thus, if you grow some kinds of plants in your aquarium, you should invest in a model with low profile LED lights to simulate your plant growth. This accessory also adds extra beauty to your tank.
Dechlorinator and water conditioners
In case you want to improve the pond water quality, you can add these treatments into the tank.
Fine Sand
This is not a vital element, but it can add more aesthetic appeal.
Big Fishnet
This tool helps you catch and keep your fish from domestic pets, wading birds, and herons while maintaining your tank.
Gravel Siphon
The gravel siphon is designed to help you change the water. Depending on your needs and budget, you can purchase an automatic or a manual model.
Thermometer
This device helps you check the water temperature to maintain a stable level all the time.
Which Brands Make The Best Goldfish Tank?
Tetra
Dr. Ulrich Baensch founded tetra Werke Company in Melle, Germany, 50 years ago. It pioneered the development of flake fish foods. Now, this brand has produced a wide range of products as well as published books for keeping aquarium fish, amphibians and reptiles, and water gardening.
Aqueon
