An aquarium is an artificial ecosystem. It is completely dependent on the person. Without human intervention, the organisms in the aquarium die. Abiotic factors are the presence of water that is at room temperature, unless of course the water is heated to create comfortable conditions for some species of fish.

The food for the fish enters the water thanks to humans, and is not produced in the aquarium.
