Goldfish gulp air at the water's surface to regulate their buoyancy and maintain proper oxygen levels in their bodies.
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."
They breathe air like betas!
Goldfish bubbles, also known as air bubbles or oxygen bubbles, form in their aquarium due to a process called "gulping." Goldfish gulp air at the water's surface, which gets trapped in their digestive system and is released as bubbles when they swim. This behavior helps goldfish regulate their buoyancy and maintain proper oxygen levels in their bodies.
It might simply mean that the water is low in Oxygen and needs replacing with fresh, oxygenated water.
Labryinth fish have air sacs and can gulp air.
Goldfish make bubbles underwater by releasing air from their gills, which creates bubbles that rise to the surface of the water.
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
Your goldfish may be making bubbles in its tank because it is trying to breathe air from the surface of the water. This behavior is normal for goldfish and helps them get oxygen when the water is low in oxygen levels.
Gulp in a lot of air and let it out
Goldfish come to the top of the water to breathe air because they have a special organ called a labyrinth organ that allows them to take in oxygen from the surface.
air. Your tank or bowl is low on oxygen. Or if you fed them, flakes.
