Many aquarists know that adult fish should not be overfed and give them more food than they can eat, because it spoils the water, increasing the amount of ammonia in it, which leads to the inhibition of fish and diseases. With fry, everything is rather different, if the fry do not get enough food for proper and good growth, they can quickly die or have poor development and inhibited growth and possibly lose the ability to reproduce.
At the moment when the fry pecks out from the egg and assimilates the contents of its yolk sac it is impossible to leave it without food for any long time.
In nature, the feeding process of the fry is solved independently, since the spawning of the fish itself begins at the moment of the spill and rains, when a large amount of plants and organic matter from the soil enters the water, which stimulate the growth of the smallest organisms that are excellent food for the fry.
At the earliest stage, when the yolk sac has only resolved in the fry, they should be fed as much as possible with live food, and the food should be present with them all the time, therefore feeding needs to be done frequently. Live food is preferable because it pollutes less water, and with frequent feeding it is a very significant factor.
Small live food for fry is sold in any pet store, but with some skill you can grow it yourself. In the first days it is necessary to feed the fry at least 5-6 times a day, and after at least two weeks you can reduce the frequency of feedings up to 3 times a day.
Feeding fry fry and viviparous is slightly different. For example, fry fry fishes in the first 5-7 days are fed by a nematode. On day 8, you can begin to feed them with nauplius.
A few grown-up fry of fledgling fishes feed on the same food as only born fry of viviparous fishes, these are small cyclops, daphnias, a Grindal worm, etc.
In addition to live food, you can feed the fry and artificial substitute, sold in the same pet stores. But even in the absence of artificial food, you can use one interesting recipe: coolly boil a chicken egg and rub a small piece of yolk in a spoon with water from the aquarium, give this mixture every 3 hours a few drops to the places where the fry accumulate.
You can also feed the fry with dry milk powder, which, with moderate feeding, practically does not spoil the water, and also floats on the surface of the water for a long time and the fry have time to eat it.
Micromin, which is specialized for fry and balanced feed, is ideal for most species of fry from the early days. When feeding with artificial food, the frequency should be significantly increased than when feeding with live food, but the amount of food itself at each feeding must be reduced.
These were the main tips for feeding the fry, in subsequent articles we will take a closer look at what each type of food is and how you can harvest live food for the fry at home.
