Fish would actually die without air because they need oxegen, zinc and water.
Water gets its oxygen (which the fish need to absorb through their gills to ''breathe'') by absorbing it from the air. If the water surface is not in contact with air, the fish will quickly use up all the oxygen in the water and die.
Water is important to fish because it provides oxygen for their respiration, helps regulate their body temperature, and serves as a medium for waste removal and nutrient absorption. Water also supports their buoyancy and allows them to move and hunt for food.

Water is to fish - as air is to animal.
Fish get their air from the water, their gills separate water form air.
fish need air because they won't be able to breath if they didn't have air, and fish need air badly because they spend most time in the water. fish need air as much as we do.
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.
no, they have a swim bladder but this is so the fish can stay afloat
A betta does not breathe air all the time, it is a fish with gills that lives in water, and it certainly looks like a fish. However, they do need to have an air space at the top of an aquarium and can survive in a wet tissue. They are fascinating fish, but they are definitely fish.
They do breathe air.
No reptiles are air breathing, cold blooded, egg laying animals. Fish are not air breathing.
If the fish has a back bone then it is considered as a bony fish :)
