During spawning of aquarium fish, a successful result is considered only if you were able to get up to 95% of healthy fry from caviar. If from the whole caviar you were able to grow no more than 20 fish, then it is difficult to call it a spawning itself.
Experienced aquarists know that providing young stock with normal food is the key to successful spawning and rearing. And we are talking about natural food, such as rotifers, daphnia, cyclops from natural reservoirs.
And it is very important that these feeds are from “good” breeds.
You should not even try to get a good yield of offspring, and in the future, good and healthy producers, if you use “homemade” feeds for feeding juveniles, such as rotifers of domestic production, ciliates of shoes, micro-feed, enkhitreusov. It is necessary to use them only in those cases if you breed rare fish in winter and you are not sure that you can get one more offspring from it in spring.
To show the importance of feed from natural water bodies for young stock, we can give the following clear example. As we know, when the red neons were brought to us in the Soviet years, they were still not sufficiently acclimatized for life in our aquariums.
They are probably still difficult to call acclimatized, since they still remember at the genetic level how the year changes at home and spawning in them takes place in the winter when it is difficult to find good natural food. The exception is the fish that were bred by our aquarists in the post-Soviet period.
And at this very time, domestic lovers of Kharacin fed their red neon feeds of home production. The results were not long in coming.
As a result of such feedings, neons became more reluctant to spawn in aquarium conditions than when they were only brought into our aquariums, and the survival rate of fry significantly decreased. The reason for this was bad starting feed home-made.
But then how did Hungarian and German aquarists cultivate red neon? After all, before you get to our country, did these fish spawn from them in the winter season?
Yes, this is true, but you must understand that in these countries were constantly selling Artemia salina eggs. Of these eggs, foreign aquarists received at home the larvae, which were excellent food, in fact, caught from a natural pond.
The best time for catching live feed from natural water bodies is the period from May to October. These six months are considered the most favorable for breeding aquarium fish in the home.
You need to go for the next portion of fresh food every day, in rare cases – every other day. As a rule, lovers are convinced that the freshly caught and delivered to the aquarium feed will be suitable as long as the crustaceans are alive.
Therefore it is necessary to take all measures that will be aimed at preserving the crustaceans in a living form. But, apparently, this opinion is wrong.
And for this you need to consider a fairly reliable example of feeding young red neon rotifers.
In the natural reservoir a good breed of rotifer was caught, and it was fed in large numbers to the fry. The youngsters did not complain about the lack of appetite, as their slightly puffed belly spoke so eloquently.
They really gave a lot of food, and its remnants continued to swim around the aquarium.
The next morning, the fry refused to eat the food. They thought they were full, but no, they decided to check. They gave the boys yesterday rotifers and they refuse to take them.
Then they gave fresh, just caught from the same reservoir as yesterday. And the picture immediately changed: the fry immediately began to use food and after 20-30 minutes their belly was full.
And at the same time an interesting feature was noticed.
From yesterday’s rotifers fry refused and preferred only fresh, which, apparently, has the best nutritional taste. How the fish were able to distinguish yesterday’s rotifers from fresh ones, God only knows, but this is a proven fact.
A similar picture was noticed, though not in such a hard variant, when feeding fry with daphnia. Such are the cases.
