Scalar calf after some time fish will appear


Caviar angelfish turned white

The spawning characteristics of the scalar are necessary for everyone who wants to support and successfully breed these beautiful creatures. The spawning process for an angelfish is an important life stage, and the breeders need to take it seriously.

Spawning angelfish

Reproduction of the angelfish is possible 10-12 months after the birth of the fish. They find a permanent pair and prepare for spawning. Females lay their eggs on wide leaves of plants, preferring the upper third of the water space. Before putting off the eggs, the female and male carefully clean the chosen place, removing the smallest particles of dirt.

The female lays the eggs, and the male swims next and fertilizes them. If, on the second day, the scalar calf has turned white, then fertilization has not taken place.

Care for offspring

Both parents take care of the eggs - they carefully remove unfertilized eggs from the sheet. Angelfish-parents are very aggressive during this period, so it’s better to spawn them in another aquarium to spawn. You can also pick up caviar from scalar and grow it in an incubator.

The incubator must be specially equipped. First of all, an air diffuser should stand near the sheet with caviar so that water mixes and the dirt does not settle on the masonry. A scalar calf that has a dull white color should be removed with a thin glass rod. The temperature of the water in the incubator should be higher than in the general aquarium - about 28 ° C.

After 2 days, the larvae will appear, and after a week the fry will actively swim and eat. To feed them you need living dust or artemia, - this is a safe food that will not carry an infection into the aquarium and will allow the fry to actively and fully develop. Juveniles grow separately from adults, in a spacious aquarium with good filtration.

The reproduction of an angelfish is not the easiest, but not a particularly difficult process: any aquarist, even a beginner, can handle it. But this does not mean that it can be approached lightly.

Angelfish: breeding at home

Angelfish are perhaps the most recognizable among aquarium fish. The characteristic shape of the body, resembling a crescent, elegant coloring and relative simplicity ensures their popularity among aquarists of different levels - from beginners to sophisticated professionals. And almost any owner of these wonderful fish sooner or later there is a desire to get offspring from them and raise it. On the reproduction of scalar at home and will be discussed in the article.

Determining the sex of an angelfish and the formation of pairs

The sexual dimorphism of the scalar is not pronounced, that is, the males and females are almost the same in appearance. Before the onset of puberty, sex cannot be determined, and even then it is rather difficult. Aquarists joke about this: "Swam - it means the male, swam - the female." However, in adults, it is possible to establish the scalar sex in most cases, although only those who are well aware of the anatomy of fish can usually do this. Let's try to figure out the grounds for determining the gender of this type of fish:

  1. Mature males have a fat tubercle-hump on their foreheads;
  2. Males have a more prominent chest carina;
  3. If you look at the fish from the front, the lower part of her body resembles a wedge, and this wedge is sharp in the male, and blunt in the female;
  4. The diagnostic sign is the genital papilla (in females, it is called the ovipositor) - an outgrowth with a hole located between the anus and the anal fin, through which the genital products come out. In females, it is larger and thicker, and in the male, respectively, thinner, sharper and directed backwards. These differences are particularly clearly seen during spawning, as well as before and immediately after it;
  5. The distance from the genital papilla to the anal fin in males is much less than in females. In fact, in males the fin fin grows directly from the genital papilla, and since the striped scalar usually has the papilla located at the base of the central band, it can be said that in the male the anal fin starts from the base of the central band and in the female behind it;

The male scalar differs from the females in a more elongated long dorsal fin. In its back there are dark transverse stripes alternating with gaps. The number of these strips in females is not more than 6, and in males there are at least 7.However, sometimes it is impossible to reliably establish the sex of the fish by these attributes, especially in artificially bred forms with marble, golden, albino color. In such cases, the sex of the fish is attempted to be determined by their behavior, when they form pairs and start spawning in the general aquarium. But this does not always work: in some cases, in the absence of males, females play their role in mating games and spawning, and same-sex couples even lay eggs (which naturally remains unfertilized).

Here you can advise the following: if you want to purchase an adult fish-producer, choose an individual with characteristic signs and behavior, or a fish that has already given offspring. Even better, it will immediately be a formed pair. If you are going to grow growers yourself, get 8-10 fry with wide and long fins, among them there will definitely be individuals of both sexes, and in the future they will be divided into pairs, and you will be able to decide which one to use for further breeding.

To form a pair of scalar prefer independently, choosing a partner of several individuals of the opposite sex. But an aquarist may well pick up a pair of available young individuals. Caught in the aquarium alone, the male and female scalaries of close age and size, as a rule, begin to "build love." It is not recommended to separate already prepared pairs and pick up other partners - for fish this is the strongest stress, and they do not always form new alliances. It is easy to determine a formed pair: the fish stick together, swim in a single file, the male begins to drive the female into the corners of the aquarium.

Growing spawners and preparing for spawning

Fish that are planned for further breeding should be kept in optimal conditions. For scalar water temperature is of particular importance, which should not be below 27 ° C. The second most important factor is the quality of the feed, future producers should eat during the whole life with live food (moth, tubule, daphnia, etc.), or in their frozen form. Angelfish, grown exclusively on dry food, are usually smaller in size, their color is paler, and they are often incapable of reproduction.

In good conditions, scalars can spawn every two weeks, provided that the eggs are immediately removed.

Males and females must always be kept together before spawning, since the preparation of males for spawning and the maturation of their genital products takes place only when females are present.

Stimulate the spawning by increasing the water temperature by 2 ° C, frequent changes (3-4 times a week at 10%), while it is better to add distilled or boiled water to lower its hardness in the aquarium. Large-leaved plants should be present in the aquarium, you can also put a piece of plastic or ceramic tile on which the scalar can spawn. Usually, fish of this genus are not deposited in a separate spawning farm, allowing them to spawn in a common aquarium.

A pair that is ready for breeding can be recognized by the female’s abdomen and its changed behavior — future parents begin to jealously guard their territory and clean the surface on which they will spawn.


As a rule, spawning occurs in the evening and lasts from 40 minutes to an hour and a half. The female lays its eggs on a previously cleaned surface, usually in even rows, the male swims up behind it and fertilizes this eggs, and so on several times, in turn. The total number of eggs is 700-800.

Incubator equipment and caviar development

Angelfish, like other cichlids, take care of their offspring, but their parental instinct is not so strong, and this concern usually lasts only 2-3 days. After spawning, the producers begin to protect the eggs from other fish in the aquarium, fan the eggs with the pectoral and dorsal fins, lift the eggs that fell from the substrate, and eat the whitened ones. In some cases, they take care of the offspring until the moment when they start feeding on their own. I must say that this care is very useful for the fry. But, unfortunately, such an exemplary behavior is more likely an exception to the rules, and usually producers just ate eggs for a few hours after spawning or after dark. Therefore, if you do not want to take risks, figuring out how caring your angelfish are, it is better to transfer the eggs to a separate aquarium 2-3 hours after spawning.

The caviar incubator is prepared as follows: a small aquarium with a capacity of 5-10 liters is half filled with water from the aquarium where the producers are kept. The second half is filled with distilled water. A heater set at a temperature of 30 ° C and an air dispenser are placed in the incubator, and after an hour the substrate with caviar is lowered there so that the caviar is washed by the current from the dispenser, but air bubbles do not fall on it.

For the prevention of fungal caviar damage, methylene blue is added to the water to an intensely blue color or the drug Sera mycopur at the rate of 1 drop per liter. It is useful to place small plants in the incubator, for example, a duckweed or riccia, they will work as a biofilter, preventing a jump in the level of nitrogen compounds in the aquarium when the fry begin to grow rapidly. In addition, ciliates and rotifers breed in the thickets, which will then become food for the fry. Lighting should be around the clock. Even if there are no plants in the incubator, it is necessary to leave the night light on at night.

The next day, the whitened eggs are removed.

Fry development and care

After two days, the shell of the eggs breaks and turns into sticky cords, on which the larvae hang, moving with the help of a tail-like flagellum. Approximately on the fourth day in the larvae, heads and yolk sacs can be distinguished, due to the stocks of which they feed. The larva is constantly moving, trying to break free from the cord attaching it.

After 7-12 days, the cord breaks, the fry begin to swim. By this time, the yolk sac is almost empty, and it is time to start feeding the fry. Fully feed them with egg yolk and dry food is impossible, so live food is prepared in advance: they breed ciliates, daphnia, and on day 5 after spawning they start to incubate Artemia. Feed the fry 5-6 times a day. It is now necessary to place a small filter in the aquarium, and in order for the fry not to go there, the lower part of it is covered, for example, with a nylon stocking. If there are a lot of fry, some of them will need to be planted from the aquarium, now their density should be no more than two per liter of water, otherwise the level of ammonia and nitrite can rise sharply. The water change is carried out once a day by a third, before feeding, previously removing the remains of food from the bottom of the siphon.

In about a month or one and a half, the fry will acquire the shape typical for the scalar, after which they will again need to be seated in a container at the rate of 4-5 liters of water per fry. At this age, they are fed with a cut pipe maker, a small moth, you can begin gradual training to live food, and after a short time settle them in a common "adult" aquarium.

As you can see, breeding an angelfish is troublesome, painstaking, but very interesting. Even if not everything comes out from the first, there will be a chance to try again, because a pair of healthy fish in good conditions often spawn. And sooner or later, a stubborn aquarist will be able to boast a flock of bright young angelfish, which he raised from eggs. Now it remains only to find them a new home, thereby increasing the number of fans of these amazing fish.

Read about the content of the angelfish in the following article, and now a short video about the spawning of these fish:

Angelfish laid caviar. After what time can fry appear? :) THX :)

Happy mommy

Caviar can do differently. If you have a separate aquarium specifically for spawning a pair of angelfish - this is good. Especially if it is large enough. If you plan to give parents their own care for caviar and fry, a couple and a brood of 200-250 fry should have plenty of room for swimming (and in a large aquarium, the couple will not have a sense of danger for the offspring, in a rush of which they can eat caviar and fry). If you do not have the opportunity to spawn spawning angelfish from the general aquarium, it is better to take the delayed caviar from the pair. The potential danger posed to scalar parents by every fish in an aquarium, and even by a partner, will cause restless parents to eat offspring. To avoid this, remove the plant or stone with caviar and place it in a special incubator, not forgetting caviar aeration, temperature inside the incubator, and general water parameters. It is recommended to add antifungal agent to the incubator so that unfertilized caviar does not harm the fertilized one.
The larvae hatch in about a day or two after fertilization, if the temperature is optimal. About a week from now, they feed on the shell of the egg they were in, so they do not need feeding. Then dry, frozen food and substitutes will make up the diet of your growing fry.

My angelfish laid eggs, what to do?


Do not disturb them. See 5-7 put the air spray. Male and female very carefully care for caviar: They fan them, eat spoiled ones. Mouth and move the eggs and larvae, guard fry. Feed your parents gently so that everyone eats. Well, more delicious ... A little bit of a shade place masonry ... Try not to make sudden movements around the aquarium. Do not worry in vain ...
And what scalar?


there are otsadniki for fry, cost about 400 rubles, transfer caviar there and fry live there
it is also possible not to prefigure anything and feed the fish well, if you do not have predatory fish, but if they are, then it’s better

With proper and comfortable maintenance the scalar regularly spawns right in the common aquarium. Usually, the next change of water and the temperature rise to 26-28 ° C serve as a stimulus for this, but the presence of a suitable substrate for laying eggs in the aquarium also plays an important role. The male and female jointly select a place in the aquarium that is most suitable for spawning, the widest leaves of aquatic plants are most popular, but often a hose coming from a filter or a piece of glass is preferred. The chosen place is thoroughly cleaned with dirt from the mouth. Then spawning itself follows, during which 400-500 eggs are harvested, on average, although a large female can lay aside a thousand. Caviar develops for about two days, during which parents diligently fan their fins, clean them of all kinds of specks and peck up the whitened, spoiled eggs. Parents in the mouth transfer the hatched larvae to another place, usually on a neighboring leaf, so that they do not side with the spoiled empty shells of eggs. Another seven days the larvae hang on a sheet under the watchful supervision of their parents, during which time all the nutrient reserves in the yolk sac are completely consumed and turn into fry, which begin to actively feed. As a first feed, it is good to use the nauplii of the shrimp Artemia salina, the well-washed nematodes are somewhat worse in nutrition (the aquarist has to breed nematodes growing independently from the culture purchased in the Bird market - such pet products are not sold in pet shops) food for fry, although this slightly increases the percentage of the dead. Generally, fry scalar are very sensitive to the quality and purity of the feed, so you should not be lazy and wash the feed as thoroughly as possible before feeding. In addition, for the first few days it is recommended to clean the aquarium from food residues and excrement regularly 1-2 times a day, it’s senseless to rely on the filter in such cases, and while the fry are small, you can’t use the pumps yet - the fry are still too weak to resist flow.
Traditionally, in the presence of other fish in an aquarium, the fry do not have the slightest chance of survival, moreover, constantly being under stress from the presence of numerous neighbors wishing to profit with fresh caviar, the parents often destroy the eggs and newborn fry themselves. Probably by the principle - "so as not to get the enemies." Unfortunately, the cause of stress may be not only the neighbors in the aquarium, but also the noise in the room where it is located, or any movement in the immediate vicinity of the aquarium - the scalars during the spawning season become very nervous. In such cases, to save the brood, the caviar is taken away from the parents and directly together with the sheet on which it was laid, transferred to a separate aquarium with a capacity of about 10-20 liters. True, all the parental functions have to be taken on by an aquarist. In order to avoid caviar damage, an anti-fungal drug is added to the fungus (the solution is methylene blue or Sera mycoprur are most known), and the whitened dead eggs are removed daily from the sheet with a thin pipette.To provide caviar with oxygen, it is necessary to place a nebulizer near the leaf, the air pressure from which is regulated so as to create a weak constant current of water for the eggs. Currently, the main industrial divorce of the scalar is carried out in this way. Of course, it contributes to increased productivity, but it leads to the gradual extinction of parental instincts in “incubator” fry. As a result, now pick a good pair that will really care for caviar and is able to hatch fry - a great success and an extremely rare event.

With the content of an angelfish, remember a few simple rules and then they will always be beautiful, vigorous and healthy:
If you have in

Angelfish laid eggs on the filter, what to do ???

Josef Schweik

Doing nothing happens. Do not touch the filter, even if it is in the same condition as it was during spawning, wait until they either transfer the fry to another place or the clutch dies.
Other fish, if they are in the aquarium and the aquarium itself is small, it is better to gently set out.
For the future: in an aquarium with scalar should be ample plants with wide leaves, all sorts of echinodorus are best suited or, at worst, cryptocorynes.

Nikolay Rubtsov

I wonder if you have a pair or one female? Usually the angelfish take care of the offspring. If the eggs are fertilized, then after two days the larvae usually appear. On the seventh day the larvae turn into fry. Feed must first washed nematodes. Successes !!

How to care for fry scalar


The first feed can be "live dust", micro-worm, in the extreme case sour milk. What is a “living dust” or a microworm, most readers probably know, but how to feed with yogurt? A small amount of "weak" milk is washed down with boiling water so that the milk protein is curled. Using a dense gas net, the clot is separated and washed with clean water. Then dip the net into the water of the aquarium and shake until a cloud of small particles of food appears. I must say that yogurt does not spoil the water. It can be stored for several days in the refrigerator.
On the second day you can give Nauplius Artemia saline and Cyclops. After two weeks in the diet is useful to include shreds and small cyclop.
When larvae are grown, it is advisable to replace water (half the volume) daily with fresh settled water of the same temperature and composition.
After 2-3 weeks the fin larvae begin to lengthen, the body flattens out; there comes the juvenile stage. At this age, the young must be transferred to a large aquarium with a capacity of at least 60 liters. Water must be aerated and filtered. At the age of one month, the young feed on a pipe maker, cyclops, and a moan
In order for the young to grow well, it is desirable to maintain the temperature at 28-30 ° C. According to S.Frank, in the Prague Botanical Garden, young scalar reaches a length of 10 cm for 3 months. This growth rate is explained by the very high water temperature (above 35 C) and the very large pool volume. I do not think that this is the strength to repeat to most aquarists. In addition, fish grown in such greenhouse conditions are very gentle and easily fall ill with the slightest decrease in temperature.

Natalia Skobeleva

I also got from caviar to get beauties of the angelfish, though I removed it from my parents.
First, caviar and fry need good aeration.
Universal pet food "Artemy-yu" (about 25 rubles) is sold in pet stores - these are Artemia eggs, they need to be soaked in water with salt and in 18-36 hours you will get live crustaceans. They can feed the fry and adult fish!
This is what experts recommend:
Angelfish parents actively care for their offspring. After two days the larvae emerge from the calf, and after 5 days the fry begin to swim and look for food. Starter feed - rotifers or cyclops nauplii. The spawn can be taken from the parents along with the leaf. In this case, it is desirable to transfer the eggs to a clean aquarium for 30-40 liters with water of the same composition and temperature (it is better to just pour out from the spawning aquarium). Next to the caviar set spray. As soon as the scalar fry began to swim, it is necessary to install a light bulb of low power for night lighting, except for daylight. Otherwise, at night, the fry will stray into corners and perish en masse.
Fry and scalar larvae are sensitive to a decrease in pH, so you should control this value and add baking soda if the pH drops to 6.5. Fry grow very quickly. The female lays from 500 to 1000 eggs. The sexual maturities of the scalar reach 10-12 months.
Good luck! //
