Because all the food in the fish tank that the fish does not eat will float down until it lands on something such as an ornament, as you said and the fish food rots as it is not eaten just like human food. Hope this helps!

-- The green is probably algae, algae grows when they're excess nutrients or light in the tank. Don't over feed so food drops to the substrate and don't have the tank lights on too long, this should cut down on algae growth.
