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.
Depending on how the fish died but most float at the surface with there stomaches facing up.

Most fish have swim bladders giving them buoyancy that allows them to "float" at various levels in water. While some species are surface dwellers other fish floating on the surface are deceased and float because of gases formed within their bodies due to the process of decay.

The balloon fish will float because it weighs less than the volume of water it displaces. By swallowing air, the fish increases its volume without significantly increasing its weight, allowing it to float at the water's surface.
fish does float on water!
No, sometimes they float on their side. But some whales have "negative bouyancy" which takes them to the bottom when they can no longer swim.
they float because they are clever

The female will lay 3-7 eggs that will float on the surface until they are ready to hatch in about a weeks time.
It depends on the species. Lily Pads have a flat surface area which allows them to float on the surface like a boat as well as having stems that keep growing until they reach the surface and then stop growing. With many Kelp species, they have "float sacs" filled with air which allow them to stay afloat.
