maintenance, care, compatibility
The test results will show two results, either everything is fine in your tank and you should look for the cause in another one, or the water is already rather polluted and you need to replace it. But, remember that it is better to change no more than 20-25% of the volume of the aquarium, so as not to change the maintenance conditions of the fish too dramatically.
If the water is all right, then you need to try to determine the cause of death of the fish. Of the most common: disease, hunger, overfeeding (especially dry food and bloodworms), long stress due to improper housing conditions, age, the attack of other fish.
And a very frequent reason – and who knows why … Believe me, any aquarist, even the one who has been keeping a complex fish for many years, has sudden deaths to watch his favorite fish.
If the incident is a single case, then do not worry – just watch out for new fish or die. If this happens all the time, then obviously something is wrong.
Be sure to contact an experienced aquarist, it’s easy to find now, since there are forums and the Internet.
Why do fish in aquarium suddenly start dying?
Unfortunately, like other living creatures, fish can die ahead of time. Why it happens? The answer to this question is often sought by novice aquarists.
It is much more effective to prevent the appearance of such a problem than to look for the causes of a pet’s death.
Ideal if you asked this question before the moment the tragedy occurred. Warned, so ready to control all the nuances of the aquarium and try to avoid the early death of aquarium inhabitants.
Consider the most common reasons.
Imagine what a fish is experiencing when it goes from one water to another, the parameters of which are significantly different. Buying a fish in a pet store, you deprive it of its usual environment, transferring it to your own, which is completely unfamiliar to the fish.
Water differs in hardness, temperature, acidity, etc. Of course, the reaction to such a change will be stress.
A sharp change in acidity of at least 1 unit indicates death for sensitive fish. Sometimes the difference in acidity is much more, so the shock that the fish is experiencing can end in death.
Proper adaptation of the fish to the new environment:
- Pour the water with the fish in a large vessel;
- Add some water from the common aquarium;
- After 10-15 minutes, repeat the procedure;
- Dilute with water to at least 70% solution.
Even if several new fish managed to survive after a crushing change of water parameters, then they will surely die in the first illness. Immunity is significantly undermined, which means that bacteria attack them first.
Carefully follow the aeration, cleanliness and new inhabitants. In the best case, the health of the fish is normalized.
No one wants to blame himself, so beginner breeders blame the disease. Unscrupulous sellers only reinforce their doubts, because they have a goal to sell expensive medicine and cash in on.
However, do not rush for a panacea, carefully examine all possible causes of death.
Blame the disease is possible only if the symptoms have been noted for a long time. The fish died away gradually, and not just died in an instant, for no apparent reason. Most often, the disease is brought to the aquarium with new residents or plants.
Death may occur due to malfunction of the heating element in cold weather.
Going to pet stores, you should be aware of what exactly you need medicine. Each of the drugs directed to a specific disease. Universal drugs do not exist!
If possible, consult an experienced aquarist or ask a question on the forum, knowledgeable people will tell you what to do in this situation.
Of course, the disease can not kill a healthy fish. Why do fish die in an aquarium? If the death occurred, then the immunity has already been undermined.
Most likely, the first two errors occurred. Do not rush to launch new residents, no matter how beautiful they are.
What to do to protect the aquarium:
- Organize quarantine for new inhabitants;
- Sanitize fish or plants.
What to do if the disease started up in the aquarium:
- Change one tenth of the water daily;
- Increase the temperature;
- Strengthen aeration;
- Remove the carriers of the disease and those who are clearly infected.
Remember which fish you ran at home last. Individuals brought from other countries can be carriers of rare diseases, to detect and classify which are sometimes not possible on their own.
Before you go to the store for pets, think over to the smallest detail, can there be several species in one fish house? You should not rely on the competence of the seller, since the main goal for him is to realize as much of the goods as possible.
A few fundamental rules:
- Big fish always tend to eat small ones (even in the case of herbivorous species);
- Many succumb to intraspecific aggression;
- Some are able to stick to small neighbors, which ultimately leads to death;
- The strong always eat the weak;
- Buy only those fish whose peace-loving nature you are sure of.
Unfortunately, it is impossible to establish why fish die. The death of a pet can happen even to experienced breeders. Be attentive to the fish, and you will definitely notice a change in behavior and in time eliminate the cause of anxiety.
More often, fish die in an aquarium because of an oversight, and not according to other criteria.
Sometimes in the aquarium, the fish begin to die one by one. Their owner makes a rash decision – he goes to the pet store and buys any funds offered by the seller.
But nothing helps. So, why fish die in an aquarium?
There are several reasons for this.
Very often, this is the reason newcomers hear from sellers to the question: “Why do I have fish die in an aquarium?” Because the latter are interested in profits from selling expensive medicines. It is important after the purchase of pets to quarantine, and sometimes – preventive treatment. But even in this case, the fish can get sick.
In this case, to prevent the pestilence, the ill person should be placed in a separate aquarium.
Imported fish sometimes bring rare species of disease that cannot be determined without special laboratory analysis. In pet stores there are a lot of drugs that can save pets from misfortune, but it’s better not to be consulted about the choice of treatment from the sellers, but from experienced aquarists.
But, as a rule, before treating the problem itself, it is necessary to look for its source: reduced immunity and, consequently, the poor state of the composition of the water.
Fish die from many causes, but the pillars of care for them are unchanged: regular cleaning of the soil and water filtration, timely replacement of water, not overfeeding.
The death of pets is always a sad event for the owners, even for those who contain only fish. Especially when they start dying one after another.
Let’s try to figure out why the fish die in the aquarium.
The first and most common reason that fish die one by one is water quality. Perhaps it has not changed for a long time, and harmful microorganisms have developed there, or, conversely, before the change the water did not settle well or had a temperature much higher or lower than necessary.
To eliminate this cause, you should immediately change the water in the aquarium.
Feed quality may also affect the fact that the fish began to breathe. Food may be expired or unsuitable for the type of fish you are keeping.
Another factor important for fish is lighting conditions. They should be optimal and as uniform as possible.
Fish can begin to breathe even in a new aquarium. The reason may be that the stores often wash aquariums, to give them a more presentable appearance.
And it is not known which ones detergents used for this. Therefore, if the fish began to die in the new aquarium, they should be immediately removed to another tank, and the aquarium should be thoroughly cleaned.
The reason why fish aquarium die can be disease, listed in the aquarium. And she can get there in different ways.
For example, with insufficiently purified water, but more often it penetrates with another, already infected fish. This can happen if you recently purchased and put a new pet in the aquarium. Particularly increases the risk if you want to keep ornamental fish and fry caught in local water bodies in one tank.
To avoid contamination of fish from a new one, you need to put each fish you just bought before going to the aquarium in quarantine, a separate container for several days.
Is it necessary to change the water if one of the fish died :: how to change the water in the aquarium :: Aquarium fish
Tip 1: Do I need to change the water if one of the fish died
Often, inexperienced aquarium owners rush to replace all the water in a tank if one fish dies, as they fear the contamination of the aquarium. So is it really necessary to completely change the aquarium water, or are there other rules for dealing with an aquarium in which one of its inhabitants died?
The question “opened a pet store. Business is not going. What to do? “- 2 answers
If only one fish dies in the aquarium and the water looks clean, it is not necessary to change it, because after changing the water, it will be necessary to wait for the restoration of the ecosystem and biological balance. Therefore, it is enough just to add fresh water, renewing the old one.
If the fish has died from an infectious disease or has lain in the aquarium for several days, the water should be replaced, while washing out the aquarium.
When adding fresh water to the aquarium, at least one third of the old water should remain – at the same time, fresh water should have similar hardness and temperature indicators.
If you still need to clean the aquarium, you need to remove all live fish and plants from it, wash, disinfect and dry. After that, new water is poured into the tank. In the first few days a short-term bacterial outbreak with water clouding can be observed in the aquarium – no need to worry, it will pass by itself.
After that, as the water becomes transparent again, plants can be returned to the aquarium, and it is advisable to launch the fish in about a week. Replacing water is often the most effective way to get rid of bacteria, but for fish it is a lot of stress, so you should not abuse it.
An electric or vacuum pump is great for changing the water in an aquarium. A siphon will also do well with this task, with the help of which the walls and bottom of the aquarium are easily cleaned of food and residue residue.
To prevent the water from turning green, the aquarium should be placed away from sunlight and turned off artificial light at night. In addition, it is necessary to periodically remove excess plants from it and feed the fish less so that the water is not contaminated by the remnants of food.
Somiki-antsitrus, which slide along the aquarium walls and eat plaque on them, will also help to clear the water.
Partial change of water in the aquarium should be done every week, changing it to 1/5 of fresh water. In order for the water to always be clear and transparent, you should launch mollusks and daphnids into the aquarium.
Many owners of aquariums are trying to clean glass containers with snails, but they are not very effective in doing this and besides they are spoiling quite a lot. Water problems are usually characteristic of “young” aquariums – later their own ecosystem arises in them, the situation normalizes independently.
The main thing – to follow the rules for the care of the aquarium.
Mini-aquariums – an attractive interior decoration. But unlike large tanks, equipped with all necessary equipment, there are some problems with care.
If you follow the basic rules, including the replacement of water, you can avoid the flowering of the aquarium and create fairly tolerable conditions for the fish.
- – soft defended water;
- – net capacity;
- – ladle;
- – scraper.
1. It is believed that a small aquarium is easier to clean than a large one. However, this is the first misconception of inexperienced aquarists. It requires more frequent replacement of water, because the products of decomposition of fish waste are accumulated here most of all.
In addition, intensive plant growth can cause a lot of trouble.
2. The water in a small aquarium should not be completely changed. It is enough to replace up to 1/5 of the total volume.
This should be done quite often – once every 3-4 days.
3. Replacement water should only be soft, room temperature, so you should have a constant supply. Only tap water from clean dishes that should be used only for this purpose.
To defend the liquid must be at least three days.
4. Replacing water in a small aquarium is not difficult. Calculate the required quantity for replacement.
For example, in an aquarium with a capacity of 10 liters, it is necessary to change 2 liters (1/5 of the total volume).
5. Scoop out the required amount of water with a special scoop with a long handle. Scrub the walls of the aquarium and add fresh soft water.
Then collect water in a clean dish and leave it to stand until the next procedure.
6. The water in the mini-tanks evaporates very quickly. Check its level regularly and top up if necessary.
7. Fully change the water in the aquarium should be as rare as possible, because it violates the biological equilibrium. However, this must be done once a year to transplant plants and clean the walls of the aquarium and filter.
8. To replace the water completely, remove the fish and place them in a jar for a while. Drain fluid with a hose.
Remove excess algae. Clean the rocks and walls of the aquarium.
9. Then pour the settled water. Add bacteria and let the aquarium stand for a couple of days, then run the fish into it.
For dwelling in a small space, choose guppies, gourami and tetra. These fish feel pretty good in mini-aquariums. Also in the pond you can settle a cockerel, neons look beautiful.
If the fish have grown to a rather large size, they need to be deposited in a larger tank.
Very impressive look and feel good in a small aquarium, not only fish, but also other marine and freshwater inhabitants, such as shrimp.
