There are many reasons for the death of aquarium fish. Ideally, the environment in the aquarium should be as similar as possible to the natural habitat of the species of fish that you have settled in it. If there are any deviations, this can lead to health problems and even death of your pets.
Aquarium fish should be provided with impeccably clean water, the aquarium itself should be well lit and filtered. And, of course, we must not forget about feeding and living plants. It would seem that meeting these requirements is quite simple, what can go wrong? Most often, fish die as a result of the following violations.
Main reasons
The first reason is poor quality water. If you don't clean your aquarium often enough, the waste products of the fish decompose and poison the water with nitrogen compounds. During the day, the fish accumulates a huge amount of feces - up to a third of its weight. Also, don't overfeed your pets, or the uneaten food will start to decompose. Unfortunately, many novice aquarists are poorly guided in such matters and completely forget about timely cleaning.
Nitrogen compounds such as ammonium, nitrate and nitrite give off an unpleasant odor and turbidity
The second reason is the incorrect adaptation of the purchased fish to new conditions. The crux of the problem is that the water in pet store aquariums and the water in your home can vary dramatically in terms of parameters such as pH, temperature, and hardness. You can't just pick up and throw a newly acquired fish into your aquarium, it can be shocked. It is necessary to attach a bag with a new fish to the glass of the aquarium, set weak aeration and add aquarium water to the bag every 10-15 minutes. After an hour and a half, the water from the bag can be poured into the sink, and the fish can be put into the aquarium.
For better adaptation of new fish, it is advisable to add a special anti-stress drug to the aquarium.
What does wrong content lead to?
The third fairly common reason is various diseases. But it is worth noting that the variant of the disease should be considered only when the possibility of contamination or maladjustment is excluded. Yes, and here it is necessary to make a reservation that the fish get sick due to a decrease in immunity caused by unfavorable conditions. If one fish has died, or a pestilence has begun, you need to consult with a specialist who is not interested in selling expensive drugs. To prevent disease, take good care of the fish, and quarantine diseased and recently acquired imported fish.
Finally, you should list the unfavorable factors that can negatively affect the health of your fish, which can lead to death. These factors include tap water, a broken heater in winter, lack of oxygen, and finally, aggression from other fish.
