Researched: fish
Aquariums fail on fundamentals, not on fancy gear. Our fish picks concentrate on the equipment that actually decides whether fish thrive — correct water volume, reliable lighting, and the test-kit habit that catches problems a week before they're fatal — with honest notes about what each kit doesn't include.
