The Kharacin family is rich in the genus Nannostomus, which is considered one of the richest in number of species. Fishes differ in modest size, the maximum body length does not exceed 6 centimeters. Nannostomuses are famous for their rich color and beautiful pattern.
The conditions of the fish are not demanding and they can easily contain a novice aquarist.
If conditions are favorable, nanostomuses can live long enough for fish of such modest size. As an example, Nannostomus Marginatus immediately comes to mind, whose body length does not exceed 4 centimeters can live for about 5 years.
Agree, for such a small fish is quite an impressive time.
Absolutely all nanostomuses have a peculiar night coloring. And it’s pretty easy to watch if you turn on the lights in the aquarium at night. You will be surprised, but your pets will not resemble themselves: instead of a beautiful pattern and longitudinal strips, oblique dark transverse stripes on a pale background will flaunt on the body of the fish.
If the fish live in favorable conditions, then they will spawn in the general aquarium. If you suddenly notice that the couple begins to spawn, fish can be caught and transplanted into a separate container, which is prepared in advance.
When you transplant fish, they will continue their mating game.
As a spawn can use a small capacity of 10 – 15 liters. As a substrate for spawning, you can use small-leaved aquarium plants, for example: Javanese moss, Cornflower, Brazilian perististille or aquatic limnophila.
Water in spawning should be soft or have an average hardness (not more than 13 degrees) at a temperature of 24 to 26 degrees Celsius.
Beckford’s nannostomus perfectly breeds at home without the use of special means to protect the eggs, because the fish do not eat it. Nevertheless, an aquarist must remember that there are wayward individuals that can show cannibalistic inclinations and eat up all clutches. And some individuals can eat eggs after the female finishes the spawning process.
However, in any case, you should periodically observe the pairs that you have spawned to spawn.
During the Nannostomus Marginatus, the aquarist should provide caviar protection. Ideally, it is better to use a separator grid with a cell of no more than 4 millimeters. The net must be pulled above the bottom of the aquarium at a height of two centimeters.
Probable gaps are best covered with small balls or pebbles. In the process of spawning a small number of eggs sticks to the leaves of plants, as a rule, they sink between the pebbles or balls.
Unfortunately, nanostomuses are hard to call highly prolific fish. In one spawning, the female of the Nannastomus of Beckford can at best sweep no more than 150 eggs, and the female of Marginatus, no more than 40 eggs.
When breeding the Nanostomus Trifusciatus, the aquarist should take into account that the fish needs soft water (not more than 6 degrees). Small larvae appear after a day, and after another 5 days the young begin to swim and feed on their own.
Artemia nauplii, ciliates-slipper or rotifers can be used as starter feed. Juveniles grow rapidly and at 6 months of age fish are ready to spawn.
The sex of the fish can be identified by special features. Many species have a difference in color between the female and the male. For example, Beckford’s Nanostomus during a spawning period acquires such a coloration as if it was drenched in blood.
But Nunnostomusa Espey is difficult to determine the floor. This species actually has no distinct differences in body shape between the female and the males, and the coloring is identical.
Despite the fact that the female nanostomus for each spawning period lay a small amount of caviar and if you have several modest spawners, you can get pretty impressive offspring: a good pair can spawn up to 5 times in a row with a break of 7-10 days. Nannotomus are a few haracin, which are devoid of fatty fin. Nannostomus Trifasciatus has populations that have a fatty fin, and some are missing.
