Incubation of eggs without parents

I am engaged in incubating fish eggs independently, without their presence. Those. As soon as they swept away, I, so that they do not devour their eggs, take it with a stone or a fragment of the substrate and place it in a pre-prepared incubator. Basically, I grow this way - chromosomes, because These "gentlemen" are constantly devouring their eggs.
What is necessary for incubating eggs without parents:
Put a separate container for the incubator, approximately 10 liters, you can even a 3-liter jar. The air diffuser is installed in such a way that the caviar is on the current of water, but does not touch the bubbles. We make disinfection of water with trypaflavine or methylene blue, even steeper will be with Tetra Fungi Stop or General Tonic from saprolegnia. Install naturally heated.
The whitened (dead eggs) are removed manually. We take a chemical pipette, of course thin and having found the whitened eggs, gently we loosen it with the tip of the pipette, to peel off the substrate. As soon as I loosened up a bit, I parted the finger, closing the pipette, and the water was absorbed along with the egg. Of course, sometimes healthy eggs are absorbed, but you do not need to worry about it, especially trying to paste them back into your place. Caviar can safely be transported by air to the incubator. In such a short time, nothing will happen to her.
Aeration at the stage of maturation should be strong, but that the eggs from the substrate do not disrupt. As soon as the first tails appear from the eggs, aeration should be reduced and the sprayer adjusted so that the bubbles are as small as possible. No pumps or filters should be placed. Eggs can simply suck in them.
Since the hatching of the larvae from the caviar and turning them into fry, it must be ensured that the surface of the water is clean. If a film is formed, it must be removed with a sheet of paper.

Spawning of barbs

I'm breeding barbs. There is nothing complicated in this. I want to share my experience in this direction. So, what needs to be done for successful spawning in barbs:
To arrange for a week of males and females, it is desirable to feed a fresh live food (especially good in this case fresh daphnia). Reduce the water temperature a little. For these days, prepare the spawning grounds (if not very large fish, then enough will be enough for a 10-liter aquarium), which naturally needs to be washed, water defended, etc. At the bottom of the spawner place some substrate, otherwise the fish will devour all the eggs. The best way is for this to fit knitted from a thin capron line or a grid with a 3-4 mm cell.
Putanka is pressed down by pebbles (pebbles pre-boil), and the grid or putanku should be placed in such a way that there are no cracks and there was a small space between the mesh (putank) and the bottom.
Grid or putanku must be boiled before putting into the spawning grounds, if this is unacceptable, then at least give a steep boiling water. Many grids from such treatment with them are strongly deformed, in this case it is necessary to soak them in a saturated salt solution or manganese, and then thoroughly rinse in running water. If there is no tangle or netting, you can sketch floating plants (for example: a naiad or Javanese moss) and press them with pebbles to the bottom of the spawner. The only drawback in plants is that they can be huge "herds" of snails, and snails are very fond of eating fish eggs.
So, everything is ready, the aquarium is washed and prepared properly, there is a knot or mesh, the barbs are seated. Now we are preparing the water. Take it from the tap and fill the spawner by half. Now let the water in the spawner settle. Now we boil a bucket of water, the upper two thirds are poured into the spawning grounds (previously cooled naturally), cover the aquarium with glass and turn on the aeration. The temperature of the water is raised to about 25 - 26 degrees Celsius, no higher. After that, in the dark, we place barbs in spawning. It is desirable to place the spawning site so that the first rays of the sun fall on it.
If the barbs are sufficiently sexually concerned for a week of separation, then in the morning there will be spawning, if not - then all of the above measures should be repeated. You can plant a couple and a whole group. With "group sex", the yield of fry is much greater, and the percentage of unfertilized calves is much less.
As soon as they saw that the fish had spawned, we quickly grab the nets and catch them until they penetrated the mesh and did not eat all the eggs. We shade the aquarium and wait for the hatching of the larvae, namely larvae, because They will become fry later.

Spawning of Danio-Rerio

Danio-Rerio I spawn practically, like guppies, I am in the sense that there is no difficulty with this process. How to do it:
Males and females hold a couple of weeks separately from each other. Then we take an ordinary 5-liter jar with ordinary tap water, settled for 3 to 4 days. In the bank, Javanese moss is laid all over the bottom. The water level above the substrate, about 4 to 5 cm.
We plant manufacturers (you can have a pair of females and 5 - 8 males). After a day we plant the fish and remove the substrate. The whole bottom should be covered with caviar.
In a few days you can repeat the whole process. The larva practically leaves after 1 - 2 days, after another day begins to feed independently.

Spawning by Gurami

How to make it so that the gurami venerated. Yes, it's very simple. For example, I do this:
Aquarium for 20 liters. The spawning is prepared in the usual way, i.e. Disinfection and so on. Female and male gourami. The temperature is slightly raised by about 2 degrees from the usual. Should be about 25 - 27 degrees C, no longer necessary. To start from above to float a little риччии.
The male will begin to build a nest of riccia and vesicles, then spawn will begin. After spawning, the female should be sedated, It often happens that the male kills the female to death after spawning.
The aquarium is shaded (eg with a rag). There should be no noise near the aquarium, especially the stomp, or the male, being afraid that the caviar is in danger will simply devour it. If there is no interest in seeing how a male cares for a nest, then it is also better to set it aside, i.e. Leave eggs alone in the aquarium. But when the larvae start licking out of the calf, the male must be planted, otherwise it will devour the larvae.

Spawning of Neonov

A capacity of 10 to 15 liters is taken. A glass or acrylic glass frame, a frame aquarium is not suitable. In principle, you can and more about 20 liters, but no more. Just more to nothing. All the same, more than 10 liters of water will not be required, just a larger area of ​​the bottom. The container is cleaned and disinfected. You can potassium permanganate - a weak solution.
The substrate is prepared. You can use Javanese moss, but then you need to make sure that there are no snails. It is better to put the nylon knob. Putanka before the use of steep boiling water. The line in the knot must be thinner. Putanka should be pressed with pebbles (pre-boil them).
While all this is prepared and gets - the producers seated, of course the females from the males (if there are no extra containers - it can even be in 3-liter cans), the water temperature drops to 22 degrees C, and the feeding improves. It is very good at this time to give a little fresh daphnia and herbal supplements.
10 liters can be planted and a couple, and 20 liters are quietly planted 2 - 3 pairs. With the latter, the result is better.
Now make the water. It is desirable to have softer water. Neon does not fertilize caviar at a stiffness of about 4 degrees. Those. For fertilization and divorce it is necessary to have water with a rigidity of about 1 degree. In short, if the rigidity approaches the boundary of 4 degrees, then the shell of the egg begins to thicken strongly and the spermatozoon can no longer penetrate through it.
Also, neons like spawn in weakly acid water. For red neon, the RN can reach 5.5 - 5.7, normal neons normally rush and at 6.0 - 6.4. Acidify the water can be a lot of folk remedies - a decoction of alder cones, a tincture decoction, etc. There are brand-name preparations for creating the right pH and the concentration of humic acids and all kinds of tannins.
For spawning, it is better to take freshly prepared water and add a glass of water from a safe aquarium to 10 liters. This is for introducing a certain amount of microflora, simply speaking for revitalization.
So, the water is ready, has an amber color and the necessary parameters. Fill it all in spawning and put it on for a couple of days in a dark corner. If a distillate was used, it is imperative to put a purge for a while. The sprayer, the net and everything else should be either well-disinfected or new, but also treated.
The temperature in the spawner rises to 25 - 26 degrees C, the purging is done very weak, so that it does not bubble, and in the evening the producers start there. The spawning grounds are shaded from all sides, a 15-watt light bulb is placed on the side, through a small hole. It is better to dig a hole, the size of a fifty-kopeck piece in a package of photo paper and make it somewhere on the side, let one corner be lighted a little, and everything else in the shade.
If everything is done correctly, then they will vynernatsya this night, closer to the morning. This can be detected by scattered eggs, if you highlight the aquarium on the side. Eggs are transparent to look at and you need to look carefully. The bulk of the eggs should settle under the substrate at the bottom. The appearance of the females will change dramatically - they will become thin and will cling to the corners, and in general the fish look faded and tired.
Now you need to catch fish with a net. Reduce the water level to 7 - 10 cm, the aquarium completely shade. Usually, it's best to put the spawner somewhere in the closet.
For the convenience of controlling the caviar, it is possible to remove the substrate, for this it is necessary to shake it well, so that all the eggs that are in the putanka fall out. Since saprolegnia in water is always - you need to add a medicine there, for example - GeneralTonik - this will reduce the percentage of loss of eggs from the fungus. Whitened (dead) eggs are removed with a pipette.
Caviar develops approximately about 5 days, then larvae hatch from it and after 3 days begin to swim. The newborn larva must get to the surface of the water and swallow a vial to fill the swim bladder. Therefore, it is necessary to ensure that the water surface is not covered with a film. Once the larvae turn into fry and move to horizontal swimming - they can begin to feed.
From the first day, a gradual substitution of water begins, at first a third for the same in composition, and then it is necessary to add a stiffer glass a day. And you can not put any filters in the spawning grounds. Even the slightest foam sponge can easily break the ridge no longer the smallest mullet. They simply attracted to the foam sponge and they can not tear themselves away from it, they die there.

Reproduction of Ancestors

Ancystrus fish is not surprisingly simple in breeding, often spawns even in a common aquarium. By and large, not at all more complex than the same speckled catfish, for example. Caviar is large, rarely spoiled eggs. For information, caviar itself is as "armored" as the parents themselves. What is necessary for the spawning of ancistrus:
1. Manufacturers. You can buy a ready-made pair, you can grow from a group of fry. Once the females are rounded, and the males grow up bushes - you can plant for spawning. Of course, you will not get much caviar from young parents, if pieces of 30 eggs will turn out well. For example, an adult female puts up to a hundred and fifty eggs. If the manufacturers were taken as adults, then we must first look at the belly, the benefit of the ancistrus is not difficult. The female tummy should be distinctly rounded, and the male should not be too sunken. Such a male will not be of much use, since he is physically weak. Strongly faded and yellowed, too, it is better not to take, there is a high probability that they are old.
2. For spawning, aquariums with a volume of 60 to 70 liters are best used. If the pair is large, then this is the most suitable for them. Well, you can put young people in 40 liters. Water does not matter much. They are equally well spawned and in the water 10-12 degrees of the total aquarium and in softened water. Therefore, all the data below recommendations will be needed only if the fish begin to somehow stubborn. Water can be prepared by simply topping boiling water, about one-third of the total volume. It is boiled in a conventional enameled bucket, then it is allowed to settle and use the upper 2/3. What remains at the bottom of the bucket with a deposit of poured. In boiled water, there is no oxygen, so you do not forget to water for a few hours then. Further, the temperature of the water is increased by 3 to 4 degrees C, from the one that was in the common aquarium. Those. Approximately 27-28 degrees C. If they lived at this temperature constantly in a common aquarium, then it is necessary to lower it for a week to 24-25 degrees C and feed well. It is advisable to plant them on full vegetable food before spawning.
Then, put a filter as high as possible into the spawner, let there be a strong current. Ancistrus is only a joy. Well, of course, all this should be within reasonable limits. Do not put the pump in 60 liters with a capacity of 1 ton per hour. As a substrate, various tubes of suitable diameter are well suited. You can plastic, only in the beginning they need to be soaked properly, as well as the one that they had in the aquarium. The tube is fixed with pebbles, and the stream of water must be directed to its side in the immediate vicinity of the entrance. Sometimes the truth is they ignore the tube they offer and lay their eggs directly on the stones, sometimes in the gap between the glass and the filter, sometimes just in the corner of the aquarium. Small ancestrs like to crawl into the tubes themselves and spawn there. So wherever they like it - there and spawn.
3. Shade the aquarium in the usual way, just cover up with some kind of rag, if even a little light gets, then nothing terrible will happen. Be sure to put aeration when the water is saturated with oxygen ancistrus like it. The producers themselves put in spawning in the evening, as a rule, in a day they will spawn. By the time - it's about the next night. If you do not spawn, then you need to leave them in the spawning farther, it happens, and so they will sit and sit and will spawn. But after the spawning of the female is better to be otasdit from the male. After spawning, the male begins to get nervous and drive the female. While Ancistrus did not spawn, but simply sit in spawning and only think that they need to spawn - they can be fed. In extreme cases, the filter will all suck.
4. After spawning the male sits on the caviar and guards it. Licking, brushing, tail swings, if the current is weak. Thanks to his work, caviar of Ancistrus never suffers saprollegy. Caviar casts rarely - the parental instinct is very strong. But if it starts to be nervous for some reason, it can eat caviar. This happens very often.
5. Fry hatch somewhere in a week. Up to this point, the male is best left with caviar. Hatching fry with large yolk sacs, they hang in a bunch and hang for a few more days until the bag resolves. Once they begin to disperse, you can give them food. Maleok is very large and therefore it can be fed even with cut pipe. It is possible to throw various tableted forages. They will sink to the bottom and the fry will cling to them.
6. In practice ancistrus often spit on water, as well as temperature and current. If they decide to spawn, they will do it in unheated, without aeration and flow, with a hard water aquarium. So the easiest way is to put spawning with a pomp, put a couple there and wait for the fry to appear. And all of the above is for more fastidious antsistrusov and just in case.

Reproduction of snails ampulla

When the laying of caviar caviar is found, for example, on the upper glass of the aquarium, it is necessary to carefully remove it from there and place it in a polyethylene lid and this lid to float in the aquarium. After a while, there are small ampoules in this very lid.

Breeding of macrophages

When spawning and further breeding of macropores, it is known that the male macropod itself cares for caviar, i.e. He chooses the whitened (dead) eggs.
And in no case it is impossible in this case to climb a pipette for the selection of dead eggs, as is done in other fish, into the nest of the macropod. From fear and stress, he will simply eat all the caviar.
