Royal Tetra in the aquarium – breeding guide

Hello, friends. The blog already has an article about the royal tetra, but it was written by me a long time ago and with the omission of many interesting points.

Today I want to add the previous material in order to fully reveal the topic in front of you.

Color Nematobrikon Palmeri is notable for its expressiveness and originality. A black wide strip runs along the body of the male.

Closer to the base of the tail, it narrows and turns into a black “braid”, which protrudes far enough from the notch of the caudal fin. Both blades are also painted black and rather elongated in length.

If you look closely, the shape of the tail resembles a trident. On sale there are individuals in which there are two pigtails on the upper tail lobe instead of one.

The fins of the fish have a light yellow color. Anal fins of elongated shape with black and white stripes.

The edges of the ventral and pectoral fins are yellowish-whitish. The location of the pectoral fins is slightly offset in the lower part of the body.

The tail, back and gill covers just above the black longitudinal strip, when reflected, glow with turquoise hues. Quite often, turquoise stripes are found in the tail immediately above the anal fin.

The end of this interesting outfit is a blue-green glowing eye, which looks extremely impressive against the general background. The maximum color range of fish reaches the age of the year.

Females have a more scarce coloration, being satisfied with only a black longitudinal strip that runs to the caudal fin and a luminous greenish eye. The abdomen of females does not stand out strongly against the general background and is strongly rounded only if it is filled with caviar.

The maximum body length of the male is 7 centimeters, the females are 1-2 centimeters shorter.

Despite the attractive appearance and quite decent decorative qualities, royal tetra is not in wide demand among aquarists. As for me, the reason lies in the low fertility of the fish, consisting in a small portion of caviar, which the female is able to sweep aside for one spawning. But, as for me, this feature can be easily and simply compensated.

The royal tetras have short spawning periods. If spawning proceeds in the general aquarium, then all these spawn will go unnoticed, as other inhabitants eat up all their eggs.

It turns out that in order to get offspring from these fish, you will have to keep the tetras constantly in the spawning farm or, more often, plant the spawners.

When breeding royal tetras, there is one trick that allows you to increase the number of eggs during spawning. For this, males and females need to be kept apart for some time and fed abundantly.

However, in this case it is very important not to overdo the females, as this may lead to their death.

The royal tetra attracts the attention of an aquarist with its behavior. If we are talking about a flock of fish, then we can see a clear hierarchical hierarchy.

When a new male appears in a flock, then immediately begin to clarify the relationship, which will continue until justice and hierarchical structure prevail.

At this time, you can observe frequent fights between males, which do not cause any physical harm to the fighting males. Skirmishes are accompanied by sharp blows to the body.

If any of the males gives up their positions, then he will squeeze the fins and turn sideways to his opponent, making it clear that he has accepted the defeat.

The male, who is the king of the hierarchical ladder, does not take part in these fights. But if the clashes concern him personally (it is necessary to remember the feathers of the bored fellow), then he begins to behave like other males.

Males-leaders try to protect their territory and chase away the rest of the fish from it. In large aquariums, one male can safely hold up to 50 centimeters of territory.

And his behavior can be so tough that if any fish swim to his possessions, he immediately abruptly turned back. And the landlord, like a rooster, stood in front of him with a raised tail.

As for me, the size of the captured territory directly affects the population of the aquarium and the personal qualities of a certain fish. A female is invited to the chosen territory for future spawning.

Since the males constantly keep within their possessions, aquarists sometimes have the feeling that he is guarding clutch. As a rule, he stands leaning slightly forward.

If suddenly he had to move, then there is a good reason for this: an intruder, feeding, or the appearance of a female ready to spawn. Females at this time can behave very freely – swim where they want and do what they want.

Royal tetra smart enough fish. Without good reason, he never fusses and is not afraid of a person approaching the aquarium. Moreover, she is well versed in our intentions.

If she sees a net in your hands, she immediately floats away into the thickets of aquarium plants and controls the actions of the aquarist. If you want to catch a guaranteed fish, you need to take it by surprise, otherwise you will drive them for a long time around the aquarium.

When the tetra sees that the danger has passed, he immediately returns to his domain.

What can not but rejoice, it is the omnivorous fish. Argued that the royal tetra from time to time should be given a few small crumbs of white bread or boiled semolina.

In preparing the producers for spawning, in addition to vegetable feed, it is necessary to introduce into the diet a variety of feed of animal origin.

During the spawning period, fish try to keep open areas of the aquarium. During courtship, the males show some fussiness around the female and tremble with their feathers.

Spawning occurs near a plant near the bottom. No matter how hard aquarists try to notice the signs of cannibalism, no cases of caviar eating by parents have been noticed.

The aquarium for spawning does not have to be large, you have enough 10-liter capacity. In the bank there should be bushes of some small-leaved plants, for example, peristististnik, elodeya, Javanese moss. To calm spawning fish, floating aquarium plants, such as a fern or a pinch, can be placed on the surface of the water.

If spawning is located in a place where people often pass, then it is better to veil the aquarium.

With good preparation, the producers planted to spawn from the evening can spawn the next day. But, it may happen that during the day the fish just sweep away a couple of eggs that you do not even notice.

Accordingly, if you want to get offspring, then do not rush to plant fish to spawn.

Aquarium water must meet the following requirements:

  • Active reaction environment 6.0 – 6.2 pH;
  • The overall rigidity is 2 to 3 degrees;
  • Carbonate hardness 0.5 – 1.0 degrees;
  • Temperature 25 – 26 degrees.

The larvae begin to hatch after a day and spend another five days lying on the ground. When the swim bladder is full, the fry will be near the bottom for the first time. At first, the young do not move much, show no reaction to the light, do not swim in search of food.

After a few days, the fry begin to move around the aquarium, mainly in open areas.

Like other species of aquarium fish, royal tetra fry develop unevenly. In one litter, some fish can grow and develop faster.

This suggests that the quality of caviar has suffered. Be prepared for the fact that some of the weakest fry will die before they reach 2 weeks of age. If there are very few fry, it is best to move them to a tank with a low water level (no more than 10 centimeters).

This will give you the opportunity to more carefully follow the fry and give less feed to maintain proper water quality.

Feed the young need infusoria and rotifers. It is not recommended to feed the youngs with saline water rotifers, as they quickly sink to the bottom of the aquarium and sedentary fry will not eat them.

More or less, the fact that on the second day the ambassadors of the young fry can be fed can be fed to the nauplii of Artemia until the moment when it is possible to switch to larger types of food.

According to numerous observations of aquarists, the young of the royal tetra withstand sufficiently tolerate an increase in the concentration of nitrite in the aquarium. But, be prepared that if such a nuisance has occurred, you should immediately take appropriate measures.

At the age of one month, the fry show a black longitudinal strip, but the fish do not show adequate activity.

At the age of one month, the body length of the fry is 1 centimeter, and after another month it is 2. From this point on, the fish can be transferred to a common aquarium and maintained with other fish. At six months of age, the royal tetra is ready for reproduction.

The first significant symptom of the separation of fish by gender is the elongated middle rays of the caudal fin in males and the rounded abdomen in females.
