Which fish are compatible with a 60l aquarium?

Which fish are compatible with a 60l aquarium? This is the question that all aquarists ask themselves at the beginning. Like any enthusiast, we know that our pets give us peace and well-being. If you like small fish, seeing them swimming, moving and dancing in all directions brightens your day.

If you have just bought an aquarium or are planning to do so, put small inhabitants there. Before knowing which fish are compatible with a 60l aquarium, it is first essential to know some basic rules. Fish are friendly living beings that can teach us a lot about their way of life. In order to ensure them a pleasant and healthy living space, let's ask the right questions:

  • How many fish should you put in a 60l aquarium?
  • What are the parameters to respect before choosing the fish?
  • and finally, what fish are made for a 60l aquarium?

1- How many fish to put in a 60L aquarium?

The choice of number of fish depends mainly on their size. In general, it is always necessary to provide 1cm of fish of adult size, for 1 liter of water. If you opt for juveniles, think about their living space when they are adults. Even if you would like to have a lot of them, always think of their well-being above all else.

  • How to calculate the number of fish according to its size?

(copy the following link: https://www.foudebassin.com/blogs/conseils/quelle-est-la-quantite-de-poissons-a-respecter-dans-un-bassin)

For a fish of adult size, about 5cm, you need 5l of water per fish. If the fish are of medium size, for example, 10cm or more, provide 10l of water per fish.

The smaller the fish, the more you can put in. For a 6cm fish for example, the number suitable for a 60l aquarium is 15 subjects.

What must absolutely be avoided is overcrowding.

  • What is “overpopulation”:

Aquatic overpopulation is similar to human overpopulation. It is the concentration of several fish in the same restricted living environment. Overpopulation unbalances the ecosystem in general.

In general, it is due either to the introduction of too many subjects in a living environment or to uncontrolled reproduction.

Be aware that the saturation of the living environment of your fish leads to unsanitary conditions. The water in your aquarium will become cloudy despite a good filtration system: when their living environment is cramped, the filtration system will no longer be able to filter the waste. The nitrite concentration and the oxygen requirement will increase and at the same time the pH will decrease. Consequently, your little ones will suffocate or fall ill, at worst they may die.

Overcrowding also promotes stress in fish. Some fish become very aggressive by dint of being numerous. You always have to keep a balance in their ecosystem.

There is another point that we must not forget: reproduction.

If you choose to put male and female fish in the same aquarium, put only very little there because they will reproduce later and risk saturating their living environment.

2- What are the parameters to respect before choosing the fish?

  • Know the biology of fish:
  • The size :

When you buy your fish from a pet store, always ask the right questions: Is their current size the adult size or their juvenile size?

If they are still young fish, ask them how big they will be when they reach adulthood.

  • Their diet:

When you buy fish, you have to know how many times a day to feed them. One of the factors that pollutes your aquarium water is overfeeding.

It is also necessary to learn about their metabolism according to the seasons. Each fish has its own way of life that must be respected.

  • Their way of life :

Before deciding which fish are best suited for your aquarium, find out about their lifestyle:

Are the fish you just bought gregarious or territorial? Are they lonely? what is their natural environment?

It is according to the answers to these questions that all your choices will be based.

  • Their natural environment:

Having pets is not just for our own pleasure. When they're happy and healthy, we'll be too.

If you want your little ones to be happy, make sure you provide them with a pleasant living environment. It is certainly impossible to provide them with a living space exactly like their natural habitat, however, you must ensure that certain elements are exactly like in their natural living environment: in particular the ph of the water where they will live, the water temperature, their diet, the symbiosis of each species: which fish can live together.

Know that fish have temperaments, instincts like any other animal. If you are going to put fish that have territorial instincts and like to hunt with those that like to live in groups, there will be conflicts in your aquarium.

3- Now we will see in detail, which species are best suited for your 60L aquarium

  • Betta splendens:

Betta Splendens are small fish of 7cm in adult size. They are commonly called: the fighters.

Pygmy sunfish are easy to care for. They live in water around 10-28 degrees C.

One of the advantages of having this type of fish is the easy control over their reproduction. If you want pygmy sunfish to reproduce, you have to reproduce their life cycle in a natural way: you have to lower the temperature and raise it little by little, following their biological rhythm.

  • Killi Cap Lopez

Cape Lopez
