A freshwater aquarium looks simple, a glass box of water and fish, but it is actually a living biological system, and every problem in fishkeeping traces back to that system. This classroom teaches the real science and skill behind a thriving tank: the nitrogen cycle and how to complete it safely before adding fish, how to choose, set up, and stock an aquarium, and the weekly maintenance routine of water changes, filter care, and testing that keeps the system stable. Whether you are starting your first tank or rescuing a troubled one, you will finish understanding exactly why aquariums work, and exactly how to keep yours healthy.
