Not all residents of modern apartments can afford the maintenance and installation of a large aquarium, so most often a small aquarium is purchased. When choosing residents for such a small artificial reservoir, several rules must be followed.
Content rules
A small aquarium should not be populated with a large number of fish. Purchase fish based on the assumption that one fish requires at least four liters of water. Considering that usually the volume of a small aquarium does not exceed thirty liters, you should not populate it with more than ten aquatic inhabitants. In addition, it is necessary to take into account not only the number, but also the size of the fish, because if rather large individuals grow out of the fry, they will be cramped and uncomfortable in a small volume of water. Consider also such a factor as the features inherent in a particular breed of fish: it is convenient for some of them to live in the lower layer, for others - in the upper one. Some species of individuals are inactive, others, on the contrary, require continuous movement. Some fish are gregarious, others prefer solitude. When you populate a small aquarium with fish with conflicting qualities, you run the risk of disrupting their rhythm of life and creating chaos in the aquarium itself.
Which fish to choose
It is undesirable to inhabit a small aquarium with predatory fish species. Fish of delicate, rare, expensive and exotic breeds are not suitable for this method of keeping, since in a small reservoir it will be difficult for you to maintain comfortable conditions for them, such fish often get sick and die.
Of the viviparous fish, the most unpretentious are the well-known guppies, they are distinguished by their mobility and very beautiful colors, their brilliant flock looks very impressive. Guppies breed well, so you need to make sure that the aquarium is not overcrowded with them.
It is quite possible to add bright swordsmen to guppies, they are also undemanding and will add bright red, black and green colors to your aquarium.
The cockerel fish is also very popular, known for its huge "rooster" tail and a variety of the most incredible colors.
Black mollies are a little more whimsical, you have to monitor the temperature and purity of the water, moreover, this fish prefers salt water.
Of the spawning fish, barbs, small zebrafish and veiled cardinals, which need an abundance of algae, are quite suitable for a small aquarium.
Also, tiny bright neons will not be superfluous, whose flocks will always enliven the aquarium and delight the eye.
All these breeds are distinguished by the small size of the fish and their high vitality. If you want to choose a larger fish, you can buy striped, sailboat-like, scalar or catfish, which, differing in their large size and bright colors, get along well with any other fish. In addition, these beautiful gold, green and speckled inhabitants of the bottom layer are the orderlies of the aquarium, cleaning the soil and walls from undigested food, dirt and algae plaque.
Thus, if you wish, you can populate even a small aquarium with a volume of ten to thirty liters with beautiful fish that will feel quite comfortable, successfully get along with each other and decorate your home.
