More water movement always increases oxygenation. Add an additional filter or replace the existing filter with a higher capacity unit, if necessary. Other options are using a powerhead, putting a spray bar on the outlet of the filter, or using airstones.
How do I know if my fish need more 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.
How do I know if my fish tank has no oxygen?
When oxygen is critically low, fish will gasp at the surface of the water where oxygen levels are highest. You also may notice them hanging out where the filter tumbles water back into the tank. Other signs include fast breathing, lethargic behavior or swimming off-balance.
Can a fish bowl run out of oxygen?
Fish Bowls Restrict Oxygen Levels
Fish bowls are usually pretty small anyway, so the temptation is to fill them all the way up. … In many cases, fish suffocate even in the cleanest water simply because oxygen cannot diffuse into the water as fast as it is consumed.
What do I do if my fish is gasping for air?
If your fish are gasping for air you should quickly oxygenate the water by turning on a hose or any other water pump and spraying the water in the air so it gets oxygenated and then lands in the water garden. Doing a partial water change is also recommended.
How do I check the oxygen level in my fish tank?
The best way to test the amount of dissolved oxygen in your aquarium’s water is with a portable dissolved oxygen meter. After calibrating the meter, you can place a probe into the tank water, and read the results on the digital display.
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 long can fish survive without air pump?
Fish can survive about two days without an air pump in completely still water. However, with the right kind of filter producing lots of surface water movement, an air stone may not be required at all.
What does it mean when fish go to the top of the tank?
The top of the aquarium contains the highest levels of dissolved oxygen as the air and water interact there. When your fish experience a lack of oxygen in the aquarium, it is natural for them to swim to the surface and will gasp for air (or gulping air).
Does a filter provide oxygen?
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.
Can goldfish live in a bowl without an air pump?
Your goldfish can live very well without an air pump, but you must keep the bowl or tank clean and include pebbles.
Can I buy a fish at PetSmart?

Why are my fish opening and closing their mouths?
Opening and closing their mouths frequently is not common for most fish. This behavior is usually a sign of low oxygen levels in the water. Because fish breathe through their gills, opening and closing their mouths allows more water (and thus more oxygen) to pass over their scales and through their bodies.
How do you oxygenate water?
A very simple way to add oxygen to the pond is to add an air pump. Sitting at the side of the pond, it will pump air through a small hose to an air stone and bubbles will enter the water. When the bubbles break the water’s surface oxygen will then be added.
Why is my fish floating but not dead?
If a fish displays such behavior it means that it has buoyancy issues. … Here’s the reason behind a fish that floats upside-down, yet remains alive: The impaired buoyancy in fish is caused by a malfunction of their swim bladder. When affected by Swim Bladder Disorder fish will often lose the ability to properly swim.
