For successful breeding and maintenance of aquarium fish, it is important to know about the duration of their life.
There are several main factors that determine the life of aquarium fish. This is primarily affected by:
- fish size;
- temperature conditions;
- proper diet;
- competent selection of neighbors.
Usually large fish live longer. Incorrect temperature conditions will shorten the life span, and a sharp drop can lead to death. When undernourished, the individual will not receive enough energy for normal life, and some species in any case can not be overfed. Keeping small fish together with a large carnivore threatens the existence of the first. And also do not forget about the special conditions of detention inherent in many species. For rare species it is even more relevant.
Size of fish
Size greatly influences how much fish live in an aquarium. Usually the smallest period is reserved for small inhabitants of an artificial reservoir. For example, fish with sizes less than 5 cm in length, such as swordtails, neons, guppies, live no more than 5 years, but usually more than a year.
But the lowest level in the water world belongs to the South American zinolebias. The life of this record small fish strongly depends on the rainy season., because drought is deadly for her. This species was saved from complete extinction by the peculiarity. timely spawning. She has time to grow and spawn caviar before the end of high water.
Medium-sized species live much more. Say, when starting a piranha, you need to understand that these fish live in an aquarium for up to 25 years. For other proportional varieties, this value is much more modest. about 15 years.
Duration may depend on gender: in males, it is usually higher. In some cases, the difference reaches two years. Often this is due to the fact that it is the female that spawns. The process not only takes a lot of resources, but is also associated with risk. Some fish die immediately after hatching. From some diseases or unsuccessful throwing of caviar, no one is immune, but more often these troubles occur in sword bearers and guppies. rather small varieties.
How much aquarium fish live is greatly influenced by the water temperature. Any cold-blooded have a problem with controlling their body temperature. It directly depends on the environment, which determines the rhythm of the body processes. Heat accelerates life, shortening life, and the cold acts exactly the opposite.
Sometimes, with a slight difference in degrees, the life span of domestic fish changes by several years. However, it must be understood that there are threshold limits at which a cold-blooded one will simply die.
In water, not only temperature is important, but also purity. If you rarely clean the aquarium, the concentration of toxins will inevitably increase. This will lead to a shortened life span and the emergence of many diseases. It is also possible dysfunction of the respiratory organs or diseases of the digestive system. all this leads to quick death. When replacing water, it should be first defended to reduce the chlorine content to an acceptable value.
Food strongly affects longevity. Obesity is quite common among fish. Especially often this happens when the aquarium is in a house with small children. The guys love to look at the fish during feeding, so they can feed them, breaking all sorts of rules. Excess food puts a lot of pressure on digestive energy and the heart.
Some species are almost insatiable, while others overfeeding can lead to early death. However, undernourishment is also a major problem. Lack of vitamins and nutrients adversely affects any organism. You can understand whether fish can live normally with the current volume of food, sniffing it. If any specific odor emanates from the liquid, this indicates a violation of the rules of the content. Well, when the water has no flavors.
In addition to the rotten smell, there are other features that indicate overfeeding:
- after replacement, the water quickly becomes turbid;
- a slippery coating appears on the algae and walls;
- film is formed.
When selecting the inhabitants of the aquarium should take into account not only the size or appearance of individuals. Much depends on the character of the neighbors. Most of the species are able to adapt to the hardness and temperature of the water, but not always to the character of each other.
When choosing a company of aquarium fish, you need to take into account their character.
Compatibility errors also lead to overpopulation, which causes such difficulties:
- lack of food and its uncontrolled distribution;
- big competition between individuals of the same or different species;
- lack of oxygen;
- high probability of occurrence of diseases;
- the struggle for leadership and aggressive behavior.
Special caution when choosing require snooty species that often kill each other due to competition. It is also important to take into account the volume of the aquarium. a certain amount of water should fall on each individual.
Many factors affect the lifespan of aquarium dwellers. Lifetime with proper content can be found in the table below.
