What is the ideal temperature range for a freshwater aquarium?

The ideal temperature range for a freshwater aquarium varies depending on the species of fish but generally falls between 72°F and 82°F (22°C to 28°C). Tropical fish require warmer water, typically around 75°F to 80°F (24°C to 27°C), while cooler water species prefer temperatures on the lower end of the range. Always research the specific needs of your fish and use a reliable aquarium heater and thermometer to maintain stable temperatures.
