In view of the various problems that occur during the production of oviparous ornamental fish, fish farming has also been said many times, but some aquarists frequently ask this question, such as why after the peacock fish give birth to small fish, the female fish will collapse and die, we can know how the state of the mother fish is through the state of the small fish that is born:
First, small fish are intact and healthy without yolk sacs
1, for most of the egg-fetal ornamental fish, as long as they are born of the small fish in a very short period of time can immediately swim in the water, or the birth of the small fish will not fall to the bottom of the tank, but directly in the middle of the water surface began to swim in the water, looking for food everywhere, then such a small fish must be the healthiest.
2, we can also say that in addition to the above situation, the small fish born, more or less physical problems, we have some problems in the water temperature and water quality, there are food feeding, we have to pay close attention, in fact, this mainly shows that the big fish have problems.
Second, small fish with yolk sacs but very small, after a day or two will be absorbed
1. Although the newborn fish has a slight yolk sac, the small fish can also swim normally after a while, and such a problem is not too big.
2, the biggest problem is that the small fish with yolk sac sinks to the bottom, does not move at all or the tail can not be extended, shrinking into a clump, such a small fish mortality rate will be extremely high.
Third, why do big fish lay eggs
The first case, of course, is that the male fish is not fertilized, the probability of this situation is not large, but sometimes there will be, so in order to prevent this situation, for the breeding of the usual oviparous ornamental fish, we are in the ratio of male and female, it is best to compare one to two.
Fourth, the most serious situation
1, we will also find that some oviparous ornamental fish, especially peacock fish in the production of such a situation:
The small fish born at the beginning of the mother fish has a yolk sac but there are still a few small fish that will swim, but then the next thing that is born is a small fish with a yolk sac and does not move at all, and even a stillbirth, until finally, the mother fish gives birth to pure eggs, basically some pure white small round grains, some aquarists do not pay attention to it and can not see at all.
2, then in this case, most of the reasons are only three:
One is that the mother fish's physique is too poor, one is that the mother fish is extremely frightened, and then the new water stimulation is too heavy, in general, if the above situation occurs, the mother fish will soon bow her back and collapse after the birth, even if we carry out effective isolation, the mother fish may die in a few days.
3, in the above three reasons, the physical fitness is too poor is generally easy to appear in the female fish we just bought home, or the ornamental fish raised by ourselves are not fed for a long time, and the water quality and water temperature are not good.
4, most of the remaining reasons are only one, that is, the new water stimulation is too heavy, which is the most likely to lead to the mass production of the female fish and even the production of eggs, because in most cases, the female fish of the oviparous ornamental fish is impossible to lay eggs if it is not stimulated by the new water, especially after the small fish are born in front, and finally even the fish eggs are discharged, which is overproduction, and then the mother fish will definitely collapse and hunch back.
5, under normal circumstances, the breeding and production of female fish, even if the number of small fish produced is more, they will not have a small belly after production, and there will never be a phenomenon of collapsing waist and hunching back.
Fifth, careful observation, careful maintenance
1, so for the reproduction of such ornamental fish, the fish farming road before and after the emphasis many times, we must not go to kill chickens to get eggs, unless we do not want to keep the mother fish, otherwise we must provide water quality is suitable, water temperature is moderate, food is sufficient, breeding water body wide environment, if they are allowed to produce in this environment, how can the above problems occur.
2. In case we encounter a peacock female with a bowed back after childbirth, can we adjust it well?
Sometimes it can really be conditioned, but this must not be too serious, if in the fish farm most of the peacock fish will be thrown away directly, there is no need to raise it again, if we can use the old green water to recuperate the female fish alone, at the beginning of the extremely slow increase in feeding.
3, the initial feeding must not be large, it is best to use live shrimp or small fish worms, it may be possible that they will slowly recover, after a few days we will find that the original collapsed stomach will be re-bulging point, and then we are feeding until full recovery, but for such a female fish at least ten days of recovery period to be able to see the effect.
4, in fact, if there are live fish and insects to carefully feed, as long as they do not die within three or five days, they can slowly get better, this situation I often encounter, but also can save them.
5, but if the mother's stomach collapses too heavily after giving birth, as if we usually say, the thin front chest is attached to the back, then it will be difficult to recover, and even in a very short period of time, it will directly die.
Therefore, by observing the state of the small fry that are born, we can easily see how the physique of the big fish is, in fact, most of these problems are caused by us not paying attention to the water temperature and water quality and nutrition in the feeding process or the breeding process, and then there is a problem in choosing fish when buying, and we can't complain about others.
This also includes the red arrow, black Mary, leather ball, moonlight peony and other oviparous ornamental fish, their mother fish may appear in the production period of the above situation, we must carefully observe, be careful!
I am a veteran of fish farming, more ornamental fish problems please pay attention, thank you!
