A flock of mobile and cheerful neons is a worthy decoration of any aquarium, both populated by exotic fish, and the very classic hobby of a novice aquarist. Their cheerfulness and original appearance leaves no one indifferent.
And watch how neons multiply – a fascinating and original spectacle.
The more conscientious preparation, the more elegant the result …
This is the motto that should inspire those who decide to play on the production of neon offspring. From the first steps it is necessary to learn that these babies do not belong to viviparous fish, such as guppies or swordtails.
Fertilization is carried out in external conditions, to which, respectively, a number of specific requirements are imposed.
The breeding of neons is a simple but crucial process that must begin with the selection of applicants for fallowing. Individuals should be:
- sexually mature (optimally aged 10-12 months);
- to eat well;
- have no defects.
Females and males are alike. The difference is in size: the female is larger and rounder than the male.
The dark band at the level of the middle of the body has a bend. The male is smaller and slimmer, the strip is flat and straight.
As it is ready to spawn in the area of the tail, it appears rounding, which gradually increases.
Male and female individuals are chosen to participate in breeding in a 2: 1 ratio, since the readiness level of the female is almost twice as high as that of the male.
Two weeks before the process, separate content of selected fish should be provided. At the same time the water temperature in these aquariums should be within 19 o.
It does not seem ridiculous, but several times it is worth making a date: sitting down selected individuals to each other for the purpose of acquaintance and habituation.

Aquarium for spawning – special attention. In the case of carrying out fallowing for one individual, the choice should be stopped on an extended one-piece version with a water volume of 15-20 liters. In order to avoid damage to the delicate surface of the eggs, the bottom is not covered with soil, although several bushes of plants with large leaves will serve not only as an ornament, but also as a place of attachment of eggs.
Instead of the ground, a special soft mesh or foam mattress can be put on the bottom, which, thanks to its cellular structure, will keep the eggs in full condition.
Javanese moss is suitable as a natural litter. However, it should not be other living creatures, for example, aquarium snails.
In order for fish to have a desire to breed, water must have the appropriate characteristics:
- maximum softness (in the range of 0.5-3);
- be clean and aerated;
- have a temperature of from 22o to 25o and a pH in the range of 5.5-6.5;
- be thoroughly disinfected, possibly mixed with distilled water;
- do not have mechanical and chemical impurities.
The aquarium can not be filled to the full height, because the possibility of jumping fish is not excluded. From above it is better to put glass or cover with a special lid.
The back and side walls in the aquarium should be faithfully shaded, the front glass should not have direct exposure to bright rays of light.
Additional water flows are not needed.
From the moment the fish are placed in the aquarium for spawning, they are stopped feeding and careful observation is established. It is better to choose for this evening hours, in which case fertilization of eggs will take place in the region of 4-5 am.
However, observing the behavior of fish during this period is a rather interesting and exciting process. The female and the males, showing interest to each other, can produce, at first glance, strange movements.
They then freeze at the same time in one place, then they begin to attack each other. The male is especially active: it coils, dorsal fits to the female, then rushes back and forth in the aquarium.
The apogee of this behavior is 200-250 eggs, which the female throws on the surface of the leaves or the bottom of the aquarium. At this point, it is necessary to completely stop the light from entering the aquarium, since it is the direct enemy of the young calf.
The attachment of eggs to the surface is facilitated by the presence of a special liquid in them, which prevents them from disintegrating or being carried away by the movements of water.
Fertilization of the eggs with their seminal fluid will produce the male, who will quickly be ready for this.
Usually the duration of such a process varies between two and four hours. After graduation, parents should immediately be sent to a common house, in order to avoid eating their own offspring.
The real enemy of eggs and, subsequently, fry – bacteria. To protect them, you can reduce the water level by 7-10 cm and add drugs such as methylene blue or trypaflavin to it.
Having ensured constant observation of the eggs, it is necessary to remove damaged elements in a timely manner (they acquire an unhealthy whitish appearance).
Caviar ripens on average during the day. The main condition for a favorable outcome is to maintain the water temperature in the aquarium within 24-25o.
Neon hatching hatches are attached to the walls of the aquarium and for the first three days they feed on the contents of their yolk sac. Approximately 5 days after the birth, you can begin to teach the young to the light.
Growing up, they gladly feed on, for example, Cyclops larvae. The neonatal period lasts about four weeks.
A visual indicator of self-viability is the appearance of a strip on the body.
Kids grow and develop well when feeding by ciliates, rotifers or simply plankton. The main thing is that food should be of guaranteed quality and safe against bacteria.
Gradually, the fry need to be accustomed to water of higher hardness. This is done by gradually adding to the water of the aquarium for spawning water from the common aquarium.
As they grow older, neon fry should be accustomed to self-searching for food. Since they are primarily able to respond to light, food is given to a certain place located in the area of local illumination.
Then the process of eating will not stretch in time and the remnants of food can be removed in a timely manner, preventing its undesirable decomposition.
As young fishes acquire basic life skills, they can be transplanted into the main aquarium, but it is advisable to get away from large and aggressive neighbors who may suspect “live food” in them.
Taking into account all the above facts, it is safe to say that such a thing as “neons: reproduction in a common aquarium” is hardly viable. There are too many so-called “ifs” on this issue.
It is better not to risk, considering that the natural craving for the reproduction process occurs in neons once a year: in late autumn – early winter.
