What Is a Self Contained Aquarium and How Does It Work?
A self-contained aquarium is a closed eco-system that typically combines fish, plants, and sometimes additional organisms in a compact setup, eliminating the need for extensive equipment or constant human intervention. These aquariums are designed with built-in filtration and sometimes circulation systems to maintain water quality without requiring frequent changes.
