In the wild, the habitat of neon includes the waters of the rivers and streams of Colombia, Peru and Brazil. The reproduction of neons in the general aquarium requires the creation of a microclimate as close as possible to the natural living conditions of the fish. Under natural conditions, the water in which the fish live is very clean, soft and saturated with trace elements released by plants and branches that have fallen into it.
Reproduction of blue neons
Under the conditions of an aquarium, breeding blue neons is quite difficult, because these are short-tailed and not viviparous fishes. This is a painstaking task requiring increased attention and practical experience. Everyone who at least once saw how neons reproduce in an aquarium is convinced of this.
Blue neons are very beautiful when they float in flocks. From the first few producers you can get young and form a good flock in the aquarium.
In order for the fish to breed, they will need to create special conditions. To do this, you can use all-glass jars, which are easy to clean and disinfect. Tanks should be filled with soft water of high purity.
Under natural conditions, spawning occurs at dawn. Therefore, spawning lighting should be diffused. Spawning can last several days.
After completion of throwing eggs, manufacturers are transferred to a common aquarium, and the tank is completely shaded, as the bright light adversely affects the eggs.
During one spawning, the female is able to postpone up to 200 eggs. The first larvae appear already after 36 hours, and after 5 days they form in full fry. After that, the ambient lighting can be submitted to the nursery. As the fish grows, the hardness of the water is gradually increased by substitution.
Selection of producers before spawning
Breeding neon at home includes a range of works on the selection of future manufacturers.
The most promising representatives, it is necessary to isolate from the general population no later than two weeks before spawning.
In appearance, the neon samochka differ little from the males. Blue neons have a peculiarity. they have females and males equally brightly colored. Usually, female individuals are somewhat larger and have a more rounded abdomen. The blue neon strip in males is straight, and in females it is slightly curved in the center.
Reproduction success and the health of future offspring largely depends on the state of the parents. When choosing manufacturers, you can focus on the following signs:
- healthy appearance;
- bright characteristic coloring;
- mobility and desire for feeding;
- age around the year.
Until the moment when the females are not ready for spawning, the selected pairs are kept separately. During this period, the neons should provide excessive feeding. Suitable feed such as: cyclops, daphnia, small bloodworm. It is not recommended to feed the fish with a chimney sweep and an Exitreus.
The most suitable time to reproduce neon in the general aquarium is from October to January. By this time, the glass spawner should already be disinfected and properly prepared.
For successful reproduction of one pair will be sufficient capacity with a working volume of 6-10 liters. If you plan to spawn up to 10 pairs, you will need an equipped aquarium with a capacity of 20 liters.
To create the necessary lighting for spawning, the back wall of the aquarium must be covered with dark paper. In this case, the frontal light should be soft and not directed.
When spawning, neons glue eggs to various surfaces with a special substance. Accordingly, in the spawn there should be a sufficient amount of algae, on the leaves of which eggs could be kept.
A good choice is to plant Javanese moss, a peristristum and a fern. You can also use substitutes, which should be strengthened at the bottom. These can be nylon nets and scourers, tangled fishing line or willow roots collected in water.
It is unacceptable to get into the spawn of snails and catfish that feed on caviar. In a short period of time, they are able to clean all the internal surfaces of the container from the eggs.
Preparation of water for spawning
Successful breeding of neons at home depends a lot on preparatory work related to water. Increased attention should be paid to such factors:
- Fertilization of caviar occurs only when the hardness of water is 0.5-4 °. Otherwise, the fry will not hatch.
- The main enemy of fry are bacteria. To slow down their reproduction in the aquatic environment, it is necessary to maintain the acidity in the range (pH) 5.5-6.5. To adjust the level, you can use a decoction of oak bark or alder cones.
- The aquatic environment for the breeding ground can be obtained by mixing distilled and water from the common aquarium. It is unacceptable to get into the capacity of snails.
- Before the fish can be run into the nursery, the water must be infused and saturated with oxygen. The optimum temperature is. 22-25 °.
Often during mating, blue neons jump out of the tank. Therefore, the water level should be 20 cm below the walls, and the spawning area is covered with a glass lid. The supply of oxygen in this case is carried out using a compressor.
After the breeding ground is ready, the selected producers are placed in the spawning farm in the evening, after which they no longer feed.
To observe how neons breed in an aquarium, be prepared to wake up early in the morning. Spawning, which lasts up to 4 hours, begins closer to dawn. In the process, the female lays up to 250 eggs.
When the fish cease to show signs of interest to each other, they are deposited in a common aquarium with a net net. Trypaflavin is added to the spawning area for the purpose of disinfection, after which the aquarium is coated with an opaque material.
The maintenance of fry at various stages of development
We proceed to the main stage of observation, as neons multiply. 36 hours after spawning is completed, the larvae appear. The first six days of life, they receive food from the gall sac and almost do not move. As soon as they pass this period, the active feeding phase begins.
- It is necessary to feed the fry in small portions and often. A favorite feed of young blue neons is a mixture of zooplankton and rotifers.
- You can add ciliates and ground boiled egg yolk.
The first weeks of life the fry are guided by the rays of light, swimming to the places where plankton accumulates. This neon feature is used for feeding. The food is deliberately placed in the lit area of the breeding ground. Thanks to this trick, the water is not contaminated by excessive amounts of protein, which helps to avoid the death of young animals due to infection.
When growing fry neon should pay close attention to the lighting of the spawning aquarium. After two weeks, when the fish become stronger, they gradually remove the blackout from the spawning grounds. Spawning is returned to normal lighting when the fry are 1 month old. Otherwise, the young may lose orientation.
When the young are three weeks old, they show a characteristic color for blue neon. By the age of one and a half months, gradually increasing the hardness of the water and introducing new feeds into the diet, they are prepared for transfer to the general aquarium.
