It's a fish that doesn't move or function and it floats. They are poisonous so don't touch them or you'll die. If it's decaying that means that the fish scales are falling off and being absorbed by the water which would make the water toxic.

They are scavengers and will eat the decaying/dead plants, dead animals (such as a dead fish) and algae. They keep the water nice and clean and the water quality up.
Yes, some fish do eat dead fish. This behavior helps to clean up the environment by removing decaying matter, which can prevent the spread of disease and maintain the overall health of the ecosystem.
Scavenger fish like catfish, carp, and some species of bottom-dwelling fish feed on dead fish. These fish help to clean up the ecosystem by consuming decaying matter and recycling nutrients back into the food chain.
Only fungi feed on dead or decaying matter.
Depending on the species of crab, its food source will vary. Crabs eat algae, water plants, small fish, other crabs, shell fish, and some will eat dead fish or decaying vegetation.

A large quantity of dead fish in one single body of water can be caused by many different things. Pollution, temperature change, and bacteria in the water are all common causes for a large number of fish in the same body of water. If the dead fish are kept in the body of water instead of being removed, this could create more of an issue as the decaying fish bodies may cause disease to spread to the healthy fish.
Dead or decaying matter is important for nutrient cycling in ecosystems. It is broken down by decomposers like bacteria and fungi, releasing nutrients back into the soil for plants to use. This process is crucial for sustaining the health and productivity of ecosystems.
