The day before yesterday we talked about red swordfish, which inspired everyone's wave of nostalgia, and also discussed an additional problem, that is, red swordfish love to eat small fish, especially their own small fish. In fact, this problem is not only the red swordfish, but also other flower mackerel, and the peacock fish is very common. So how do you avoid such a situation? Why do they eat small fish, are they really the meanest or hungry?

This may be a mystery, why do you say so? This is different from many other spawning fish swallowing eggs, swallowing eggs is likely to be because of being frightened, and this directly eat small fish, we sometimes think that the stomach is hungry after childbirth, so eat supplementary nutrition, but careful observation will find that in fact, even if the male fish that is fed, it will also eat small fish. So, would it be a natural thing to eat some small fish to make sure they don't rob them of more finite resources when they grow up?
Up to now, there is no unified conclusion, probably because there are too few people who have studied this part. In fact, it is more difficult to draw conclusions, but most of the consensus now is that they mistake small fish for food.

Although it is the nature of the fish itself, it can still be avoided through human intervention, mainly in two ways, the first is to artificially create a natural environment, so that small fish naturally avoid danger, and the second is to artificially isolate large fish and small fish, so that they cannot contact and protect small fish.
Let's start with the first, a method that mimics the natural environment. In fact, in nature we have no human intervention, if the small fish are eaten by the big fish, naturally there will be no species to meet us, so nature has long been in the dark to make arrangements, this is also the method I more respect, the operation is not difficult, is to arrange the fish tank environment dense water grass, more dodge, the best gap more, so that the small fish can hide into the gap, and the big fish can not go, you can protect the newborn small fish very well. Because the small fish of the flower mackerel basically has the ability to swim just after birth, this pure egg-grown ornamental fish can be very different.
The second method, in fact, is also used more, perhaps the first method gives everyone an illusion: it looks difficult. Therefore, most of the aquarists have chosen the second kind, directly isolating the big fish and small fish, and the simplest way is to put the big fish (the female fish to be produced) in the isolation box, and then the small fish is born, and you can pass through the gap in the isolation box to a relatively safe space, because the big fish cannot pass the gap.
In fact, the second method can also be artificially when the big fish is ready to be produced, every time a small fish is born, the small fish is fished to the safe fish tank, but this operation is basically difficult to jam the time point, and there is not much time to wait for the big fish to be born there, so now basically no one uses it.
If it is used in the isolation box, although it is convenient, there is a very bad place, that is, it is easy to put the mother fish in the suppressed space of the isolation box to produce anxiety, and then it is likely to die of nervousness before it is produced. Yes, you heard it right, it's really nervous to die, I'm sure aquarists who have had the same operation have all experienced this, and I've heard aquaters have such a description more than once, it can be said that such a tragedy is staged every day. So I personally prefer the first approach.

Don't mistake small fish for having a container for them, but if you think so, you'd be wrong. Because small bodies of water can easily breed bacteria, why? Because in the feed you feed, those who have not eaten will be a reason for the food to be eaten for a long time. It's just that bacteria can't be seen with the naked eye, so it's easy to ignore them.
And the small fish itself is not completely long, so the resistance and immunity of the body are naturally not as good as the big fish, the big fish may be able to stay in such a space for a long time without getting sick, but the small fish can't. If the newborn fish stays in too small containers (in fact, too small water bodies) for a week, basically a little observation will find that some small fish have begun to pintail, which is a manifestation of bacterial infection tail, and such a small fish is basically difficult to cure (the current technology is like this). That's why I'm more of a fan of the first method, because the water is larger and closer to nature.
If you also like to raise ornamental fish, you may wish to pay attention to it, all you want for fish farming is here.
