Compatibility of fish in habitat — the burning question in the aquarium.

It excites both novices and experienced lovers who want to make new species of fish, constantly appearing on the market.

Conditionally can be divided on the compatibility of biological, behavioral, and aesthetic .

The biological compatibility of the fish to set easier other: are different species living in the biotope, such as temperature, salinity, pH, oxygen saturability, securenote plants, type of soil (rocky, sandy, etc.) and other factors.

An example of a complete biological incompatibility: settling in one tank of goldfish and cockerels . Goldfish like cool, clear water, no rough vegetation, and abundant aeration. The ideal temperature for keeping cockerels . 29 degrees, they like heavily vegetated accept slightly stagnant water (biotope “pond”) . aeration in such quantities as for goldfish, they don’t need: in which case, they will always be able to capture the air from the water surface.

Another issue of biocompatibility — kurmoyarskaya fish.

If the fan is not planning to feed your fish different types of forage daily, it is necessary to select fish species that require more or less identical food. But it is simple: most species are omnivorous, and will eat live food . or industrially-produced under wide type of species of fish, dry food, with one fasting day a week, which can be fed with feed of plant origin .

Thus, to establish biological compatibility of fish is quite simple: it is necessary to examine the conditions of detention of various kinds, to look at the conditions of their origin (warm-water ponds with stagnant acidic water, the cool river with alkaline water, etc.). In the case of coincidence of the parameters as follows: temperature, hydrochemistry, nitrogen metabolism, food requirements, etc. fishes can settle in one habitat.

Failure to comply with the biocompatibility factors quickly leads to disastrous results, while the nonobservance of the factors of behavioral compatibility of Pisces gives the result much slower.

More difficult is the issue of behavioural compatibility of the fish . will the various fish species to interfere with each other in the tight space of the aquarium, annoy each other, “pinch” and to drive each other from their territory and, as extreme aggression: to injure or eat each other.

Even fish from a single area of settlement, with the same biological compatibility, can be compatible behavioral habits, such as viviparus guppies can not tolerate the proximity of a large group of live-bearing swordtails . trying to hurt the beautiful tails of gopasex .

Very often, even small fish can seriously drive their larger neighbors, which will cause the latter deviations and subsequent disease. However, the fight for territory characteristic of most species of fish, the only question is how badly they will treat their neighbors.

So before buying it is necessary to thoroughly study the character and habits acquired species of fish.

Certain species of fish protect their territory, even attacking and driving away all approaching relatives. Other fish only aggressive during spawning.

Even the same species can have different compatibility depending on your age and gender: for example, fry goldfish gets along well with the neons . while the adult “scrofula” will eat neons for a sweet soul; males in one tank can only live one male, otherwise guaranteed posypanny tails.

Schooling fish should be kept in groups, pairs — in pairs.

All this must be considered in the planning of the biotope.

In General, there is a rule: large and predatory fish are kept away from small and herbivorous. Ideal for the beginner — it neons, guppies, a honey gourami, Rasbora , some catfish corydoras to the bottom.

Also need to consider behavioural aspects in nursing .

Large and frisky fish usually distilled off small and slow with the feeder.

This problem is solved by the arrangement of several feeders on the surface of the water or removing feeders from the habitat, the introduction of new kinds of food, such as tablets, which are fast sinking and allow the fish to eat the feed in the water column and on the bottom, not at the trough.

However, in some cases it is better to divide the fish, for example, many cichlids (apistos, cichlasoma) . pupfish (pike, aphyosemion) have a habit to “study” the food before eating. The more high-spirited neighbors: tetras, barbs, Rasbora may eat all the food for them. The same applies to fish with longfin swimmers, some because of their slowness, they are best kept separate from fish with normal fins.

Therefore, proper selection of behavioral compatibility of Pisces — the task is quite complicated and requires a good knowledge of the behavior and habits of a species of fish, and a novice aquarist almost always makes mistakes when checking their first habitats. However, over time, learning to create “songs of the fishes”, an Amateur will be able to enjoy the species differences in behavior are properly selected, various groups of hydrobionts.

As for the aesthetic compatibility of the fish . universal advice is difficult to give here.

In General form they look like this: a big fish in a small flock looks ugly and feels uncomfortable, at least in this case there should be two large fish; motile zebrafish amid the slow-moving gourami look very not harmonious; on the whole, the flock of small brightly coloured fish well with three or four large, but not very bright, especially against the backdrop of lush greenery.

This should add selection of fish species by layers of water . preferably the filling of different layers for aesthetic purposes.

However, here the author’s imagination can be boundless, and perhaps he’ll find his Forte in the refutation of the known truths of the aesthetic compatibility of aquarium fish.
