Ammonia and Nitrite poisoning harm the gills of fish, which leads to respiratory stress. This may be the reason you’re seeing your fish dying and gasping at the top or the bottom of the tank, right after a water change.
Why are all my fish at the top of the tank after water change?
A fish may linger near the surface because he’s trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.
How do you save a dying fish after water change?
Here are a few tips for the next time you perform water change:
- Don’t clean the filter and gravel on the same day.
- Don’t perform large water changes randomly.
- Clean the filter only 2 days after the water change.
- Clean the filter once 4-6 weeks. Don’t overdo it.
- Keep fish in the tank during 20-50% water changes.
How do I oxygenate my fish tank?

How do you treat a stressed fish?
Trying a stress coat product, which can help remove chlorine, neutralize chloramines and detoxify heavy metals to set up optimal water conditions. It can also help heal skin wounds and torn fins. Reducing overcrowding by moving additional fish to a new tank, or getting a larger aquarium.
How can you tell if a fish is in shock?
Some fish succumb to pH shock immediately. Others may exhibit symptoms including thrashing, darting, gasping, swimming near the water’s surface and trying to jump out of the tank. Such symptoms are the same as those that indicate toxins in the water — either cause is serious.
Why are my fish stressed after water change?
What is this? Osmotic shock may be the reason why fish suffer when you remove a large portion of the Nitrate ions through changing the water in their tank. When in Osmotic shock following a water change, freshwater fish will hold too much fluid, which may lead to swelling of their organs, a condition known as Dropsy.
How do you destress a fish tank?
Ways to Reduce Fish Stress
Change water frequently to keep nitrate and ammonia levels low. Try adding water conditioners like API Stress Coat Aquarium Water Conditioner, which is formulated to reduce fish stress by 40% by removing dangerous toxins.
What does a stressed goldfish look like?
Strange Swimming: When fish are stressed, they often develop odd swimming patterns. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
How do I know if my fish tank has enough oxygen?
The most telling sign that your fish need more oxygen is if you see them gasping at the surface — they will also tend to hang out back by the filter output. This area of your tank tends to possess the highest oxygen concentration as it is near the most disturbed surface.
Do bubblers put oxygen in water?
Aerate the water
Bubblers add oxygen to your aquarium.
What are some signs of ammonia stress in a tank?
Signs of Ammonia stress
- Lethargy.
- Loss of appetite.

What is new tank syndrome?
The new tank syndrome means quickly rising nitrite levels in water leading to a very high level. Afterwards, the nitrite concentration sinks again. Nitrite is toxic for fish and can even be fatal in higher amounts. The water parameters in the aquarium should therefore be checked regularly and altered if necessary.
Why do my fish swim up and down the glass?

As a response to hypoxia, some fish are able to remodel their gills to increase respiratory surface area, with some species such as goldfish doubling their lamellar surface areas in as little as 8 hours.
How do you increase oxygen in fish water?
The best way to increase oxygen is to increase the surface area of the aquarium. Increase Surface agitation or water movement on the surface. This allows more oxygen to dissolve and more carbon dioxide to escape. You can also add a source of fresh oxygen by installing an air pump.
