They breathe air like betas!
Goldfish gulp air at the water's surface to regulate their buoyancy and maintain proper oxygen levels in their bodies.
Labryinth fish have air sacs and can gulp air.
Goldfish make bubbles on the surface of the water by releasing air from their swim bladders through their mouths. This process is called "gulp breathing."
No they are mammals. they have to surface and breathe in a gulp of air and dive back dow. they are just like whales sorta.
puffer fish

Gulp in a lot of air and let it out
No, Bettas actually have something called a labrinthiform organ behind their gills. This allows them to store some oxygen, and they tend to gulp air from the surface. If you are going to have a lid on the Betta's home, be sure to leave a small air gap between the waterline and the lid for them to gulp from.
Several species of Catfish are actually equipped with rudimentary lungs. These lungs allow these specific catfish to "gulp" air from the surface of the water and survive even if the water is not aerated.
There is a large number of different types of fish that have air sacs and can gulp air. These fish species are referred to as "labryinth". The by far most popular Labryinth fish is The betta Splendid or Betta fish.
Gulp gulp gulp
Corydoras fish swim to the surface primarily to gulp air, as they possess a specialized swim bladder that allows them to extract oxygen from the air. This behavior is particularly common in low-oxygen environments where dissolved oxygen levels in the water are insufficient for their needs. Additionally, they may surface to explore their surroundings or find food.
