It’s not nice to see a dead fish in an aquarium. It seems to be doing everything right. Clean water, there is a filter, a hot water bottle, all the conditions for the fish, but why the fish die in the aquarium, what is the reason is not clear. This situation often arises among newbies, unknowingly they themselves are ruining the fish.
It should immediately be understood that if the conditions in the aquarium are close to natural, then there will be no problems. The fish will be healthy and will not get sick and die accordingly. Most often the fault of the death of the fish is not a disease, namely, the wrong content of fish.
Why do fish die in an aquarium?
Poisoning aquarium fish with nitrogen
Nitrogen poisoning. quite common in beginners. Who have no experience at all. Who are trying to feed the fish to the dump, those who believe if the fish eats, then he wants to eat. But it is not. Fish will always be there. In connection with this, the volume of waste products increases, and the fish may die from overfeeding. But not everyone knows the process of decomposition of feces, such nitrogen compounds are released into the water:
All of these compounds are poisonous to fish when they accumulate in large volumes. The most dangerous of this is ammonium. It is because of him that the fish most often die in the aquarium. This happens in a newly launched aquarium.
Where ammonium in the aquarium
- Increase residents in the aquarium
- The filter does not cope with this volume
- Constant overfeeding of fish
How to lower ammonia in an aquarium
- Water changes, daily at 25 percent of the volume of the aquarium
- Settling water, at least a day before pouring into the aquarium
- Install a filter designed for your tank.
The temperature of the fish tank
Water temperature may be involved in the death of the fish. Increased or decreased water temperature, as well as sudden jumps can destroy water inhabitants. There are opinions that drops of 2-3 degrees will not affect the health of the aquarium fish, but this is not the case.
Oxygen supply to the aquarium
The fisherman, as everyone knows, breathes air that is dissolved in water through aeration. If there is no aeration, then the fish has nothing to breathe and it dies. On such a phenomenon is rare if the aquarium is not overpopulated.
Diseases of aquarium fish
Nobody wants to blame themselves for death, and everyone is inclined to believe that the fish was sick. And sellers can only agree with you, because their goal is to sell fish and medicines for their treatment as much as possible and make money on it.
But do not immediately think that it was a disease. If there was a disease, the symptoms were visible long before. The fish slowly fades away and then dies. Usually, diseases are transferred with new fish or plants that have not been quarantined before being brought into the main aquarium.
Aggressive aquarium fish
Before buying fish of different species, look on the Internet whether they are compatible, whether they will get along in one aquarium. If they cause aggression to each other, then one of them will die early or later.
- A large fish will try to eat a small one, whether it is a predator or not.
- 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.
Watch the fish and if there are any signs, symptoms of the disease, immediately look on the Internet. And you can save your pet. With the death of the fish, it must immediately be removed from the aquarium, as the process of decay occurs quickly due to the high temperature of the water and the multiplication of bacteria, the turbidity of the water begins. Other inhabitants of the aquarium may also be infected.
