    Promising review: "I bought this light to replace a larger footprint LED fixture. For me, the 48 to 60-inch was perfect because it lights up the entire 72-inch aquarium with no problems or dark spots. The weather modes simulating clouds is super cool, and looks more natural than just a typical super bright light. Definitely recommend this product, and glad I could find it through Chewy!" —Twiffy

    Price: $44.39+ (available in four sizes)

    8. An aquarium heater – it automatically keeps a comfortable temperature so your fish never overheat or freeze to death. The built-in electronic thermostat helps maintain a temperature of 75 degrees, and as one reviewer said, "My fish are now more active because they’re warm."
