Oxygen.
Yes. goldfish breathe water so if a goldfish is out of water it cant breathe so it will suffocate
yes
Because goldfish cant breathe on buses :)
a) Goldfish (all fish) breathe through their gills b) All fish (Including Goldfish) suck water in through their mouth and pass it through their gill filament's.
They use their gills. However, oxygen is still crucial.
A goldfish is not from the fish type of anabantid (labyrinth fish) who would actually really drown if they do not swim up to the water surface to breathe.
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.
Cause They Like Swimming Side Ways
i have no clue what you are talking about Yes you can play with goldfish but what the heck you can also eat them.. eat them and you will gain immortality, you will be able to swim fast and breathe underwater...
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.
Goldfish may hang out at the top of the tank because they are trying to get more oxygen from the surface of the water. This behavior can indicate that the water in the tank may not have enough oxygen for them to breathe comfortably.
Your goldfish may be gasping for air due to low oxygen levels in the water, high levels of ammonia or nitrites, or poor water quality. It is important to check the water parameters and ensure proper aeration and filtration in the tank to help your goldfish breathe comfortably.
