In the article I will consider the compatibility of aquarium fish. I will list the main parameters that should be considered when selecting fish for one aquarium. I will give a table of compatibility of the most popular aquarium inhabitants.

How to choose the right fish for one aquarium

Compatibility of different types of fish is one of the main problems faced by an aquarist when starting a new aquarium or when buying new tenants.

Incorrectly chosen neighbors become a real problem and cause the death of the fish. It is necessary to take into account factors that will help the fish feel comfortable.

Compatibility table

All aquarium fish can be divided into three types of compatibility:

  • C. compatible;
  • Y. conditionally compatible;
  • H. incompatible.

The health of the fish

The fish should not be lethargic, faded, with stripped fins and any external signs of disease (white spots on the scales or partial absence of the latter, inflamed eyes, ulcers on the body, etc.)

Predators and prey

If the fish is a predator. you should not settle innocuous little neighbors. they can be eaten immediately.

Intraspecific aggression

Schooling fish is better to buy from 4 pcs. in order to save them from stress. "Harem" fish (for example, Betta Fish) need to keep a few pieces, but in this case, there should be 2-3 females per male.

Territorial aggression

Some species of fish actively protect the area. This occurs both during spawning and in order to protect pasture. Aggression can be directed to the representatives of their own species or to all the inhabitants of the aquarium.

Be sure to keep in mind that some fish protect their territory

Settling in different layers of water

They live in different layers of water and, populating an aquarium, you need to take this fact into account. Residents of the aquarium will not always be in one layer and it will look much more beautiful.

Aquarium parameters

Heat-loving fish are not settled with cold-blooded ones, but lovers of soft water with their neighbors, who prefer vodichku on tougher.


If fish are distinguished by large veil fins, it is not recommended to settle them with snooty schooling representatives. For example, barbs will quickly bite the tails of the veil tails or telescopes.


According to the general rules of large inhabitants, it is better to settle with large ones, predators with predators, slow-moving with slow-moving, etc.

In this case, the fish will grow together and can simply get used to each other. It happens that the angelfish live in peace with the neons who grew up with them, but immediately eat the "new ones".
