Good day! You absolutely correctly approach the issue of the appearance of an aquarium in your home. If it is wrong to combine the fish, their content will cause a lot of trouble to the owners. So, what fish will not "fight" in the aquarium and will be peaceful neighbors?
Aquarium Fish Compatibility
For many years, experienced aquarists have recommended combining fish from several groups:
- calm view;
- temperamental appearance;
- potentially aggressive;
Over time, however, this technique was recognized as ineffective, therefore, other, more complex selection systems were developed. Unfortunately, they also could not make life easier for the owners of aquariums.
The recommendations that will be presented below are very reliable. Nevertheless, much still depends on the nature of the individual, as well as on what conditions of life he had before getting into your aquarium.
Get fish by fry and grow them together. This will allow to get along well even relatively incompatible species.
1 category: small and timid
- Fire Tetras (Erythrositis);
- Blue neons (ordinary neons);
- Glass Perches;
- Ghost Shrimps (glass shrimps);
- Honey Gourami.
Between themselves, these species get along perfectly, and many of them are quite unpretentious creatures. It should only be remembered that such fish are incompatible with most other species.
2 category: small, peaceful species
- The Swordsmen;
- Sickle Neons (Bloody Tetras);
- Decorated Tetras;
- Copper Tetras;
- Black Neons.
These fish live collectively, so get a few individuals from each species you like.
3 category: relatively peaceful and active
- bream-shaped barbs;
- Sumatran barbs;
- shark balls;
- green and two-color labo.
Moderately aggressive fish, compatible with each other. Fry grow quickly. Adults require a 100-liter tropical aquarium.
4 category: relatively peaceful, territorial species
- shell lamprologusy;
These are relatively small fish (6-8 cm) with a bright color. A couple of individuals need a 50-liter aquarium.
5 category: extremely aggressive species
- black-striped cychlasmas;
- Mieck Cychlasma;
- diamond cichlasomes;
- black-striped albino cymes
- ophthalmic cichlinomas.
For many aquarists, this fish is attractive precisely by its temper. Indeed, it is quite interesting to observe how these creatures find out the relationship, protect the fry. Adults need an aquarium from 200l.
Who are they compatible with?
- cuckoo catfish;
- older labo.
6 category: aggressive predatory species
- black and red astronotus;
- tiger astronotus;
- astronotus albinos.
Combining this type of fish with other suitable individuals, remember that they will need an aquarium of at least 500 liters.
Compatible with large:
7 category: aggressive territorial species
- Labidochromis, etc.
All species of African Crown Chambers Mbuna. Very restless group of fishes living along the coast, among stones. Adult individuals vigorously defend their territory. Keep them should be groups of 12-15 fish, no less. In small flocks, large individuals oppress smaller ones. A dozen of these fish require an aquarium of 300 liters. Think over a large number of shelters, otherwise they will be stressed because of the inability to hide from a potential predator. Females of cichlids bred eggs and fry in the mouth.
a group of Australian irises:
- Three-streaked melanotenia;
- Melanotenia iridescent;
- Pterigoplicht brocade;
- catfish type Sinodontis.
8 category: active swimmers, relatively aggressive territorial species
- Malawian cichlids of the Utaka group;
These fish conflict with the above described species. They should be acquired in groups of at least 12 individuals, otherwise the strong will suppress the weak. These are very active fish that are in constant motion. Adults require an aquarium of 500-700 liters.
- catfish Sinodontis;
A group of perfectly matched fish. Aquarium not less than 150 liters and a height of 50 cm. Compatible with cuckoo catfish.
10 category: pack predators
It’s about piranhas. Absolutely incompatible with other species. They are distinguished by a strict school hierarchy. To contain two dozen of these fish should be in an aquarium of not less than 700 liters. Feed should be regularly, otherwise they will bite or kill weaker individuals.
11 category: decorative goldfish
Need a cold-water aquarium. One adult fish requires 40 liters of water.
Strongly incompatible with the fish from the next group!
12 category: pond fish (Koi carps and comets)
- Carps Koi;
- white, red and red-white comets;
Get along well with each other, but will not tolerate nearby neighbors from the previous group.
Beginners, especially children, I recommend to give preference to fish from the first category. They are very peaceful and not picky about their living conditions.
