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.
Why are my fish swimming at the top of the tank?
If oxygen levels are low, fish hang at the surface and gasp, as the surface has the highest oxygen level in the tank because its in contact with the air. … If oxygen is to blame and you don’t remedy the situation many common species of fish like tetras will die.
How do I know if there is enough oxygen in my fish tank?
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.
What do you do when your fish keeps floating to the top?
Flaky fish food floats at the top of the water, so when fish take a bite they also gulp down some air. This can cause their organs to become enlarged, leading to swim bladder disorder. Try soaking fish food before adding it to the tank so that it will sink into the water, allowing fish to eat it without taking in air.
Is too much aeration bad for fish?
Too much oxygen in water can lead to the potentially lethal gas bubble disease, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes. (Excess nitrogen, however, is a far more common cause of this disease.)
How can I oxygenate my water without a pump?
Here are the simple steps:
- Take any type of clean cup, pitcher or another container, scoop out and fill it with aquarium water.
- Hold the filled container some distance above the aquarium, and pour the water back into the tank. Repeat this process numerous times.
How do I fix low oxygen in my aquarium?
Filters go a long way toward increasing oxygen in the water, as they cause water movement at the surface where oxygen exchange occurs. Filters should take in water at the bottom of the tank, and release it back into the aquarium at the surface, thus distributing oxygenated water throughout.
Do fish get sad when other fish die?
No, fish do not get “sad” if another fish dies. Fish do have a brain that is capable of some type of “emotion” but not to the extent that humans feel. They don’t feel anything like sadness, but may feel something to a smaller extent. Scientists have been able to train fish.

Will swim bladder go away?
Depending on the cause, swim bladder disorders may be temporary or permanent. If your fish has a permanent swim bladder disorder, they can still live a full and happy life with some lifestyle modifications. … With any buoyancy disorder, you will need to introduce hand-feeding.
How do you revive a dying fish?
