Compatibility and combination of aquarium fish species

The choice of inhabitants for the aquarium is a very interesting, but not easy task. They have to choose not only in appearance, but also take into account other factors. Every beginner and experienced aquarist is faced with the issue of compatibility of aquarium fish.

When an aquarium is settled, it is important that its inhabitants do not conflict with each other.

The main criterion for selecting aquarium fish is their compatibility.

Not every species can peacefully exist with each other, so it is better to take care of the selection of good neighbors in advance.

Basic principles of aquarium fish compatibility:

  • by temperament;
  • on nutrition;
  • in size;
  • by content.

By temperament, fish can be by nature very aggressive. This applies to all tsikhlovym.

You can not combine them with peaceful fish, having a modest size. The barbs bite off the fins to their cohabitants; therefore, their proximity to the voile fish, which attract attention with their pronounced fins and tail, is undesirable.

There are species of fish that are considered territorial. They guard their spawning grounds and attack everyone who is in the aquarium, not excluding their relatives.

These features in the nature of the fish must be considered when settling an aquarium.

Individuals that have received strong hypertrophied traits as a result of selection (albinos or individuals with large eyes, long fins, etc.) have a very gentle character, therefore they are recommended to be populated with fish with similar temperament.

Fish are divided into predators and feeding on vegetation. However, any fish that prefers to see plants in its diet will not abandon feed of animal origin (for example, bloodworms).

With frequent consumption of animal feed, the wards start to ache because of digestive problems.

Predatory individuals who prefer to hunt at night, attacking any small peaceful fish that they can swallow. Suction Fish Can Hurt Even Neighbors, which exceed them in size if there is a lack of any vitamins in their diet.

Predatory inhabitants of the aquarium do not get along well with small fish

The golden rule: fish get along better with individuals of equal size. The most peaceful large fish will not miss the opportunity to eat a small fish that fits in her mouth.

If you add a fry of a large breed to small individuals, then when it grows up, feasts on its neighbors.

Small representatives will experience stress next to a large individual and feel threatened. In such an environment, the fish begin to ache, lose their color and just hide in the thickets.

Therefore, in the same space should live fish of about the same size.

In terms of content, ryks are cold and warm. If they live together, cold-water representatives quickly age and die.

Fish that love soft water and hard-water representatives can live together, but soft-water inhabitants will not breed in the wrong water.

Some fish eat plants, filling up the lack of plant foods; some species simply dig in the ground, damaging aquarium plants. It is necessary to take into account such peculiarities of fish behavior for their comfortable coexistence.

The following parameters should be considered: lighting, water flow rate, salinity, etc. There is a fish compatibility table that describes in detail which fish are compatible in the aquarium and which cannot be kept in the same territory.

Based on the table, we can distinguish three types of compatibility:

  • compatible;
  • conditionally compatible;
  • incompatible.

Aquarium fish compatibility chart

For a comfortable living of fish species of limited compatibility, it is important to consider the following factors:

  • aquarium size;
  • territory zoning;
  • shelter;
  • life style of a specific fish.

Relatively compatible fish is best placed in the aquarium at the same time when they are still fry. This increases the possibility of their further happy coexistence.

Overcrowding aquarium entails aggressive behavior even among the most peaceful fish. In order to achieve the perfect combination of species, it is necessary to rely not only on the compatibility table of aquarium fish, but also to reveal the individual characteristics of each particular species.

Angelfish may behave aggressively towards smaller fish.

Angelfish are gregarious species. Get along well with their relatives.

Other fish, inferior to the scalar in size, they pursue and arrange fights. However, it is possible to avoid such a situation if you plant them in an aquarium even by fry at the same time as fry of other species.

Barbusses – representatives of the active schooling species. If the aquarium contains more than six individuals of this type, do not avoid a fight.

They are difficult to get along not only among themselves, but also with other species. They have a special passion for lush tails and fins – they bite and pinch them.

Cockerels by definition fighting fish. Males have more aggression. Two males in the same territory will continuously conflict, but the combination of two females and one male is quite acceptable.

Small bright fishes with magnificent tails and large predators are especially attacked by cockerels.

Cichlids are also aggressive in nature. A fight can occur in any neighborhood, because the fish is territorial and is always ready to rush to the defense of its territory.

To reduce conflict, it is recommended to settle with individuals that will be similar in temperament and size, even fry.

Danio – small fishes, who live in a flock and have a very active temperament. They bring great inconvenience to slower fish, and they themselves often become victims of fights because of their bright tails.

It is best to get along with neighbors who do not differ in large size.

Danio fish get along best with the same small inhabitants of the aquarium

The corridor is a kind of catfish. Perfectly exist with peaceful neighbors, for example, with goldfish.

Living in the same area with an aggressive barb fish can be disastrous for the corridor.

Guppies – tiny fish with a fairly peaceful temperament. They feel most comfortable with their neighbors of identical size or slightly larger.

If you make the wrong choice, you can often lose the tail or be eaten.

Not every fish is ready for a certain neighborhood. Any aquarist should be familiar with the characteristics of the life of each individual species. This will ensure that the fish peaceful coexistence and an ideal environment for life.

Otherwise, you should always be ready to replace the equipment, change the design of the aquarium to provide shelter or buy a new fish in place of the deceased.
