By my own understanding when a fish breathes in oxygen through the gills from the water it goes into its lungs, just like a human respiratory system.
So surely if a fish dies it will still have air inside of it. Air as we know is less dense compared with water and anything filled with air in water; tends to rise.
If the lungs are on he under side of a fish surely this would make the fish tend to roll onto its back and be 'upside-down'

I've had two guppy fish die and they have both sank
they float belly upl... they float belly upl... float and, you don't really need to know because it will be easy to tell that it is dead.
it will float as long as it is not fully covered water.
When a fish dies, its body becomes heavier due to the gases produced during decomposition. This causes the fish to sink to the bottom of the water instead of floating to the surface like live fish.
