Today, there are a large number of species of aquarium fish. Before filling the aquarium with residents, it is necessary to study all the features of the content, nature, behavior, disease of individuals, as well as their compatibility. Description of the types of aquarium fish will help beginner aquarists.
Compatibility
When filling a home reservoir with different types of aquarium fish, the principle of compatibility must be taken into account. In one aquarium, you can put fish that have similar requirements for the conditions of detention.
The living conditions of cold-water species of aquarium fish can be different. Some require a lot of oxygen, so the aquarium should be large, and the water in it - up to 20 degrees. Others do not need a large amount of oxygen, they easily tolerate temperature fluctuations. Such fish are recommended for beginner aquarists.
Warm specimens feel good at a temperature of 18-20 degrees. Some species can easily tolerate lowering the temperature to 16-18 degrees. All warm-water species of aquarium fish do not need a large amount of oxygen, with the exception of cichlids and high-fin mollies. With them, it is good to contain labyrinth fish (a species of warm-water), which adapt to life in oxygen-poor water, as well as cold-water ones.
High-finder cichlids and mollinesia require a large-volume aquarium with dense vegetation.
Peaceful and aggressive fish cannot be populated into one aquarium, since in this case specimens that cannot stand up for themselves can suffer.
It is important not to overpopulate the pond. The size of the aquarium should correspond to the number of inhabitants. It should have both secluded places and free space for swimming.
