What should I do if one fish in the tank keeps chasing the other?

Isolate the fish that bites other fish, raise more fierce fish alone, some fish can not be polycultured, some fish will be more lively, some fish are quieter, fish with similar personalities are more suitable for polyculture together, fish of similar size can be polycultured together, such as zebra and many light fish can be kept together, zebra is more active but it is small so it can be polycultured with many fish, but not with koi.

Or carnivorous fish are raised together, otherwise they will be reduced to food, you can buy a quarantine box to isolate the fish that bite other fish, or put it in a fish tank similar to it for polyculture.

If it is a male fish chasing a female fish, it means that it is necessary to mate the tail, and it is left alone, and when it comes to sexual maturity, the fish has this behavior. If not, it may be that the fish is aggressive and wants to eat another fish, then you have to divide them into tanks. Otherwise, maybe that fish will really become a delicacy for this fish

This shows that these two fish are not suitable for keeping together, always fighting, if you continue to keep them together, the other one will be killed sooner or later, it is recommended to keep them separately.

In this case, it is best to keep them separately. Otherwise, sooner or later, something will happen.

Only by keeping them separately, if you keep them together, maybe one of them will be eaten.

In the process of raising ornamental fish, we will find that when a fish is sick, it will be chased by other healthy fish. The fish is already unfortunate when it is sick, and it should be protected, so why did its companions do the opposite and kill the sick fish?

In nature, many fish have a habit of swarming, swimming together, foraging together, and defending against predators. In the harsh living environment, it is difficult for weak individuals to survive, and collective strength can make up for the shortcomings of individuals.

In this big family, because of the large number of groups, they can intimidate their natural enemies to a certain extent, so as to protect every weak individual.

This is the result of hundreds of millions of years of evolution, and weak individuals unconsciously get together to keep warm. Each individual will be sheltered by the collective and contribute to the collective.

When a fish is infected, its sluggish action will drag down the whole group, and if everyone takes care of the sick, it will affect the collective action, and when dealing with natural predators, it will bring greater losses to the whole group.

Normally, sick and weak individuals will leave the group on their own and find shelter on their own to hide from predators. If it continues to follow the group, the fish will attack it for the benefit of the collective, expelling it from the group.

In our aquarium, when we find a fish cowering in the corner of the tank, we can conclude that it is infected. Other healthy fish don't forgive the sick fish just because they're cowering in a corner, but think they still have a place in the group. Because the fish tank is too small compared to the natural water body, no matter how the sick fish escape, the entire fish tank is the sphere of influence of the fish.

Therefore, when there is a sick fish in the fish tank, it will often be chased by other fish, we should divide the tank as soon as possible, carry out ** on the sick fish, and put it back into the main tank when it recovers health.

There are also people who think that when a sick fish appears, other sick fish are afraid of being infected and attack it, thinking too much, and the fish do not have such a high IQ.

It is instinctive to attack sick fish, and this behavior will help us to judge the health of the fish and identify which fish is sick as soon as possible.

Separate them. This keeps both fish safe. And there's more room to move. It's also good for fish.

The fish want to get rid of the bacteria on their bodies, chase the bites of those sick fish, hope to bite off the bacteria on the sick fish, and prevent it from infecting other fish.

The methods to disinfect the fish tank are:

1. Fish out the fish and raise it separately, put the water in the tank away, then fill the tank with clean water, and then pour some potassium permanganate into the tank.

Powder bubble tank for more than half an hour, put the water away, then put clean water, and then put a little dechlorinated water and sea salt, sea salt has the effect of sterilization and anti-inflammatory, and is harmless to fish, is the most commonly used medicine for the prevention and treatment of fish diseases, fish stores are sold.

2. At the same time of disinfection of the tank, it is necessary to disinfect the fish, the method is to put a handful of salt into the water of temporary fish raising, put more, until the water is a little salty, and the salt also has the effect of sterilization and anti-inflammatory. Then soak the fish.

For about three minutes, don't soak for too long, too long will marinate the fish, then change the water, and wait for the fish tank to be detoxified, you can put the fish in to raise.

3. If there is still a problem, you can put some yellow powder.

In the tank, yellow powder is a special medicine for various bacterial fish diseases, and it is harmless to fish, but after putting yellow powder, you must be oxygenated, because yellow powder will consume oxygen in the water and suffocate the fish to death. By doing this, your fish will basically stop chasing and biting!

It can't understand you, so it can only be raised separately, and some species of fish cannot be mixed.

You can release the fish that bites the other fish separately and raise it, because if you put them together, sooner or later the other fish will be eaten by it.

In this case, it is recommended to separate the fish in a small space.

In this case, I think it should be separated from the fish that bites the fish and let it be in a separate tank so that that doesn't happen.

Xiaoyu always bites other fish, and the other fish are bitten to death, what should I do? In fact, there are many fish, he lives alone, he doesn't like to live in groups, so he will bite other fish, and you can only live happily if you keep this fish alone.

As you said, it should be singled out and kept alone!

The water environment inside the tank changes, causing a fish to get sick. Sick fish will be chased and bitten by other fish.

When there is a large amount of foaming in the water in the fish tank, it is due to the increase in the protein content in the water, and the water quality begins to deteriorate. There are many reasons for the increase in protein content in water, the most common are:

Excessive feeding of feed, hydrolysis of residual feed;

Dead fish carcasses decomposed;

Too little water exchange.

The amount of protein in the water increases too much, and it is easy for the fish to get sick. The most effective solution is to change the water extensively to dilute the protein content.

It should be noted that too much water change can easily cause discomfort to the fish, so keep a small amount of continuous water change.

Fish in general gnaw on other fish. Indicate that the gnawed fish is sick, and look closely at the gills of the fish. If there is any anomalous object attached to the surface of the body, and if there is grass in the tank, then fish out the fish.

It is raised with water from the original tank. Add a little salt, put a little nitrofuracillin (the one that sells fish) and see how it goes.

Increase the space to move: Old fish chasing new fish to bite may be due to lack of room to move, and the keeper can move them to a tank with plenty of space so that they can move well.

Keep food sufficient: After the new fish enter the tank, the keeper should try to ensure that the food is sufficient, and the old fish will not chase the new fish to bite after they are full.

Quarantine: If the old fish are chasing the new fish to bite, use partitions or other objects to isolate them.

The old fish are always chasing the new fish to bite mainly in the competition for territory, because the fish have a certain sense of territory, after joining the new fish, they think that their territory is encroached upon, and want to drive out the fish that have encroached on the territory. It is also possible that they are fighting for food, and when they don't have much food to get their hands on, they will fight for food. If the old fish bites the new fish is not serious, there is no need to intervene.

However, when the keeper finds that the bite of the new fish is more serious, it is necessary to isolate them properly to avoid injury and death.

It may be tail biting, that is, mating, raising some aquatic plants in the fish tank, so that the fish can successfully throw off the seeds.

There are many reasons why a fish in a tank may be bitten by other fish.

Some fish, there is a sense of territorial territory, so they will expel other fish, of course, the skin of the scavenger is very hard, and they will be bitten, and the fish do not really want to eat them, but only expel them, and there is a sense of territorial territory, so they will expel other fish.

It is also possible that the fish is sick, weak, and easily attacked by other fish.

Let's start by telling me what kind of fish you have, and we'll help you analyze that there are some small tropical fish that like other fish, like tiger skins, and they like to chase the fins of the gods.

I don't know what you mean by gnawing, small fish gnawing big fish? Big fish won't hurt.
