Why do bettas gasp for air?

So why do betta fish gulp air? Betta fish gulp air at the water's surface as a supplementary means of absorbing oxygen. Unlike most other fish who can only draw oxygen from the water using their gills, betta fish have an additional labyrinth organ
labyrinth organ
Labyrinth organ

It is formed by vascularized expansion of the epibranchial bone of the first gill arch and used for respiration in air. This organ allows labyrinth fish to take in oxygen directly from the air, instead of taking it from the water in which they reside through use of gills.

which works very similarly to a set of lungs.

How do I increase oxygen in my betta tank?

Increasing water movement is the quickest way to increase oxygen (O2) levels in a fish tank, as it allows more O2 to dissolve and carbon dioxide (CO2) to be released. This can be easily done using an air pump, performing large water changes, manually stirring the water, or placing a fan near the aquarium.

How do you oxygenate water?

Aeration can be achieved through the infusion of air into the bottom of the lake, lagoon or pond or by surface agitation from a fountain or spray-like device to allow for oxygen exchange at the surface and the release of gasses such as carbon dioxide, methane or hydrogen sulfide.

Why do fish gasp at the top of the tank?

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.

Can you put too much oxygen in a fish tank?

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.)
