If the fish is dead it may sink. Otherwise a fish can go anywhere in the tank by using its swim bladder. If the fish seems to be struggling to get to the surface, the fishes swim bladder is damaged and the fish should be euthanased.

How did my fish tank magically clean itself?

I suggest that you learn more about your fish in your aquarium. One of your fish might be a bottom sucker which means that they eat all of the dirt on the side or bottom of your tank. If one of your fish are bottom suckers, that's probably the reason why your aquarium is clean. If none of your fish are bottom suckers, than somebody must be secretly cleaning your tank for you.

Why do dead fish sink to the bottom of the tank?

All drains lead to the ocean, but when your fish dies, it is actually better to bury it because if it died from a disease,then the disease could survive the sewage system and stay in sink water.When people fill up their fish bowls, the disease could still be in the water, killing hundreds of local fish.
