How to choose fish for an aquarium?
Today, many beginner aquarists are wondering what kind of fish they would like to contain. When choosing a fish, it is necessary to take into account the conditions of its keeping. Before buying new residents, you should know about them: habitat temperature, water hardness, compatibility with other species, displacement for one or more individuals. All these little things will manifest themselves in the illness of your wards, if you ignore them. Before aquarium fish arrive in your home, they need to prepare a home in advance. Naturally there will be an aquarium as a home. The aquarium should be spacious and have all the necessary equipment. Also, it must be launched according to all the rules. Do not bring fish until your aquarium is at least two weeks old. This is due to the fact that before the inhabitants appear in the aquarium, the biological balance must be established. Also at this time, the nitrogen cycle passes and the aquarium matures. Pioneers should be unpretentious viviparous. Two weeks after launch, release 2-3 guppies into the underwater world. If the fish feel good over the next week, then you can slowly launch the fish that you planned.
If you already have inhabitants in the aquarium, then new residents must be quarantined for some time. As a quarantine, there must be an additional small aquarium. The same aquarium can be used as a spawning home for fry. It is also possible to plant and treat sick fish into it. When quarantining fish, add a small disinfectant solution to the water. As such a tool can be malachite blue. This product can be purchased at any aquarium store. It will help you overcome the symptoms of fin rot and various parasites.
Now let's talk about the dimensions of the fish. Your pets should have a lot of space for swimming, places for shelters and much more. For example, if it is a catfish, then it needs underwater snags and broadleaf plants. If a flock of small fish, such as neon and zebrafish, then they need to free the foreground of the aquarium so that there is where to swim. The volume of water per individual is usually calculated depending on the size of the adult. If an adult fish grows up to 3-4 cm, then it needs 3-4 liters of water, 6-8 cm - more than 10 liters. But this rule does not apply to larger fish, as well as to schooling. Fish between 10 and 15 cm usually need 50 liters per tail. But remember that no one forbade to plant neighbors of other species to her. The main thing is that there is no overpopulation, and the fish do not drag out. Tightening of fish occurs due to improper maintenance. If a large fish grows in a small volume, then its body will be spoiled and the life span will obviously be reduced. The volume per flock is also calculated from the size of the fish, but here the whole flock is taken immediately.
In every home underwater world there should be fish that help clean the walls of aquariums, soil and plants. Catfish with suction cups successfully act as such fish. Choosing such a bottom territorial fish, remember that she also needs volume for a good life.
