About the size of the aquarium
When you go to buy an aquarium, the first difficult question is which size to choose.While location and price are also factors in the selection process, another important consideration for people who keep living creatures is the number of creatures that can be placed in it.To use a goldfish analogy, goldfish are fish that can double in length in a year or so, depending on the species. Therefore, even if they are fine when they are small, you may have to replace the aquarium after six months or a year.Therefore, we recommend that you always consider "how many animals of what size will fit" before purchasing.Now, please check how many goldfish can fit in the size of a commonly sold aquarium. (In this case, the number is written assuming a body length of around 5 cm, which is often seen in goldfish scooping.)
| Width × Depth × Height (mm) | Water volume (L) | Number of fish |
| 300 x 300 x 300 | 25L | 2 to 3 |
| 450 x 300 x 360 | 40L | 5-6 |
| 600×300×360 | 60L | 10-12 |
| 900 x 450 x 450 | 160L | 20-25 |
| 1200 x 450 x 450 | 180L | 30 to 35 |
About the material of the aquarium
2. Made of acrylic
The aquarium is made ofTwo main types: glass and acrylicThere are However, glass aquariums are generally used most often. Acrylic aquariums are very durable and have high transparency, but they have the disadvantage of being easily scratched and expensive. Therefore,People who use acrylic aquariums are fine with glass, except for those who keep the largest species of tropical fish.
About the shape of the aquarium
There are three main types of aquarium shapes.
2. Angle-less aquarium
3. Frameless aquarium tank
Water tank with frame
What is a tank with a frame?
The framed aquarium is the most common form of aquarium tank that we have seen for a long time.A feature is that there is a frame at the top of the tank and other parts of the tank. This makes it easy to install an upper filter, lights, etc.In some cases, they can be put on if the size is just a little bit too small. Another feature is that they are inexpensive. Compared to other types of aquariums, it can be purchased for as little as two-thirds the price. The only drawback, however, is that they are not as good looking as other types of aquariums because of the frames and other parts.
Advantages of framed tanks
Inexpensive
Disadvantages of framed tanks
angleless water tank
What is a cornerless tank?
Angle-less aquariums are made of a single piece of bent glass without a front glass-to-glass joint.The features of this system are that you can see all the expressions of living creatures and aquatic plants when observing them. The most important point is that there is no need to clean algae and moss from the joints of the corners. As those who have been using the same aquarium tank for a long time know, mosses and other algae form on the glass-glass joints, and even if you clean them, they will soon appear again, which may be stressful for some people. With a cornerless glass, there are no joints, so moss is less likely to appear. Of course, there are drawbacks. The disadvantage is that since the aquarium is made by bending a single sheet of glass, the glass is almost always thicker, so the weight of the aquarium is proportionally heavier. And it is a drawback that is unique to this day and age,When you take pictures of your pet animals for social networking sites, the inside of the water may appear distorted because of the crooked corners. Therefore, it is fine to observe them, but when taking pictures of them, you need to be careful not to include the corners.
Advantages of cornerless tanks
Enjoy the creatures from any angle.
Disadvantages of cornerless aquariums
It can be distorted when taking pictures, etc.
Frameless water tank
What is a frameless aquarium?
A frameless tank is an aquarium tank that can be made to look as if it has been cut out of the water without any frames.The feature of this type of tank is that it looks very good and allows you to enjoy living creatures from any angle. The most popular type of aquarium tank is the frameless aquarium tank. Until a decade ago, the joints were not very good and water would leak out after a short period of use, but in the past few years, technology has improved dramatically and water leakage has become less of a problem. The disadvantage is that since there is no frame, you have to use a special frameless upper filter and light, so the initial cost tends to be higher. Also, the bottom of the tank is not protected, so there is a risk of cracks in the bottom glass due to impact, etc. Make sure to use the supplied aquarium mat.
Advantages of Frameless Aquariums
Enjoy the creatures from any angle.
Disadvantages of frameless aquariums
Must have only aquarium mats on the bottom.
