How long can fish breathe out of water?
by
Fish can live out of water for between ten minutes and two months, depending on the species. Typically, amphibious and brackish water fish can survive far longer out of the water than freshwater fish species. Neon tetras and guppies can’t survive for more than ten minutes when out of their tanks.
Taking a fish out of water will naturally cause it to suffocate, as it isn’t able to pull oxygen from the air with its gills.
Do fish die instantly out of water?
Without respiration and oxygen an organism cannot live for more than a minute and when a fish is taken out of the water, its supply of oxygen is cut off which leads to the death of fishes in just a few minutes after taking them out from the water.
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don’t technically drown, because they don’t inhale the water, but they do die from a lack of oxygen.

Why fish died outside the water?
When the water reaches the fish via its mouth, the dissolved oxygen is taken inside and the carbon dioxide is released. – When fishes are taken out of the water, the supply of oxygen to the fish is reduced as they cannot respire using the oxygen present in the atmosphere. Thus, they will die when taken out of water.
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
