Many people who have fish as pets in their homes need to pay close attention to a number of factors that must be taken into consideration about aquariums.

Such is the case of calculating the liters of your aquarium and how many fish you can put in, as well as knowing the nature of each species that will live in it, to prevent them from harming each other. In addition to having the necessary implements and accessories to achieve the correct cleaning and care of the aquarium.

How to calculate the liters of your aquarium?

To create an aquarium that is the right size and meets the parameters set for the amount of fish population, certain mathematical formulas are used to make these calculations.

In this case there is the rule of 1 cm of fish per liter of water. The size of the aquarium will be established taking into account the number of fish, the size they will reach when they are adults, and if the aquarium has decorations , substrates, plants, live rocks, among others. This will have an impact on the total volume of water, often having a variation between 10-15% less than the size of the tank.

Keep in mind that this type of calculation only works as a rough estimate, which you can't stick to 100% as the rule doesn't take into account modern filtration systems, whether or not you have live plants, and lighting. appropriate or the type of fish.

What calculation to use?

As a general criterion for normal situations, the rule of 1 cm of fish per liter of water works well and is very easy to calculate the liters of your aquarium . This rule is used in square or rectangular aquariums.

If you use it, always do it with the net liters of water, and take into account the size that the fish will reach when it is an adult, as well as its shape. To apply this formula and establish the water capacity that an aquarium can have, you must have the width, height, and length, all divided by 1000, this measurement will give a volume or water capacity in liters.

Volume= width x height x length /1000

If the tank is unusually shaped, you should use the surface rule, which is obtained by multiplying the width of the tank by the length of the tank and dividing by 1,000.

Volume= width x length

Thus, as before, the surface area rule is not perfect. Its main advantage is that aquariums that have an unusual shape are taken into account.

How many fish can you put in an aquarium?

The population in an aquarium is a determining factor, since this will directly affect the survival of its members, that is why the size of the fish and their ability to mobilize must be taken into account.

The fact that there are both males and females of the same class in the same aquarium causes lack of control and overpopulation. For this reason, a separate area called the farrowing area must be kept where the small fish will be placed and thus achieve their survival.
