nitrite poisoning
Nitrite poisoning occurs almost exclusively in newly established pools. Many beginners are too impatient and don’t wait for the nitrite peak before buying their first fish.
Why are new fish dying in the aquarium?
Mass die-offs, in which many fish die within a few hours, can usually be traced back to poisoning. Nitrite poisoning, which can be traced back to incorrect care, is particularly common. Ammonia and ammonia poisoning are also caused by care errors.
How fast do fish die from nitrite?
If the nitrite levels are very high, the entire fish population can die within a short time. However, nitrite can also lead to long-term damage. The fish can still die after weeks or months.
Is it normal for fish to die in the aquarium?
A common cause of fish kill is excessive temperature. Often the fish only swim around apathetically, lie on the bottom, or gasp for air on the water’s surface. Check your aquarium heater and measure the temperature using an aquarium thermometer.
Why do fish just die like that?
Possible causes of fish deaths are fish diseases, lack of oxygen, or intoxication. In rare cases, strong fluctuations in water temperature are also the cause of fish kills. Hydroelectric power plants also cause numerous dead fish; Eels are particularly badly affected because of their size.
Can Fish Die From Stress?
Fish, like humans, are affected in their performance by stress. This includes not only the health of the animals but also the growth performance relevant for the fish farmer. Permanent strain (in the sense of stress) can only be avoided by optimal posture
How do fish behave with nitrite poisoning?
The clinical picture of the symptoms of nitrite and nitrate poisoning shows clear parallels to a lack of oxygen. The affected animals breathe heavily, move their gills violently, gasp constantly, and prefer to remain on the water surface.
Where are dead fish in the aquarium?
Otherwise, he will sink to the ground. A dead fish floating on the surface can easily be removed from the aquarium with a net. In a dead fish that has sunk to the bottom, further gases are produced by decomposition, so that after a while the fish also rises to the surface of the water.
What if a fish is on the bottom?
Fish swim at the bottom when they are scared. This can be caused by overly rough behavior on the part of the catchers, or it can be caused by the stress of moving to a new aquarium. Another reason for the fear of the fish can be a too-light aquarium floor, a lack of planting, or predatory fish.
Should you feed fish every day?
How often should I feed the fish? Never feed too much at once, but only as much as the fish can eat in a few minutes (exception: fresh green fodder). It is best to feed several portions throughout the day, but at least in the morning and evening.
When is the fish dead?
Bleeding can take minutes or more than an hour for the fish to die. In the first 30 seconds, they show violent defensive reactions. At lower temperatures or when stored on ice, it takes even longer for them to die.
How long do you have to wait before you can put fish in the aquarium?
It is difficult to give an exact time when you can finally put in the first fish. Experience has shown that you should wait at least 3 weeks. In some aquariums, the running-in phase takes 5 to 6 weeks, but also significantly longer.
What to do when fish is dying
A major water change can help here. Before you dispose of the dead fish, take a good look at it again. Where do you dispose of the dead fish? Smaller fish can easily be flushed down the toilet, larger animals are better thrown away.
How do fish suffocate in the aquarium?
If the oxygen saturation of the aquarium water is insufficient, there is a risk that your fish will suffocate. However, gasping for air at the surface can also be a sign that your fish do not have enough oxygen in their blood despite sufficient oxygen saturation in the water.
Which fish can go straight into the aquarium?
Live-bearing tooth carps, such as guppies and platies, or catfish have proven successful. The advantage of these fish is that they also eat algae and thus naturally prevent the aquarium from overgrowing. Because they are very small, the fish are also suitable for nano aquariums.
How do fish behave when there is a nitrite peak?
Nitrite oxidizes more hemoglobin to methemoglobin than the fish can convert back through enzymes, and therefore the bloodstream cannot adequately oxygenate the fish in the presence of nitrate.
