How long after fish die do they float?
by
After the fish dies there is no more DO being ingested and the air in the bladder starts to dissipate, causing the fish to sink to the bottom. After a few days, the internal organs of the dead fish decompose and a gas is formed. This gas causes the fish to once again float.
Oxygen remains in the bladder after a fish dies. Additional gases are released during decomposition. “The fish is like a closed container,” says Boriek. “As the fish decomposes, gases fill the body cavity.” The belly becomes a guts-filled balloon and the fish floats to the surface.
Is my fish dead or sleeping?
It’s pretty easy to tell when fish are sleeping: they lie motionless, often at the bottom or near the surface of the water. They are slow to respond to things going on around them, or may not respond at all (see some sleeping catfish here). If you watch their gills, you’ll notice they’re breathing very slowly.
