Yes, actually it must be in water. If the goldfish is not in water, it will die due to suffocation.
What else would you expect them to swim in? Of course Goldfish swim in water.
Freshwater
change water
No
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.
A damaged swim bladder.
The same reason you run more actively with air in the atmosphere. Without air, and therefore oxygen, you and the goldfish will suffocate, making it difficult to swim or run.You take in oxygen through your lungs; the goldfish takes in oxygen through its gills.
because they are fish
NO. Unless there in ranch
Anywhere :)
