Tropical fish are those that require heated water, generally in the range of 75-80Â°F (24-27Â°C). Because many homes are not kept in that temperature range day and night, these fish require a heated aquarium.
For typical freshwater fish, the temp in my aquariums is between 70 and 78 F. There are others that require higher or lower temps, for instance blind cave fish can take 63-75 F, and Bettas as high as 70-85 F. Saltwater aquarium fish typically come from the tropics, so 75-80 F is best.ach species will have an ideal range of temperatures. You should research every specie you keep and do it before purchasing. If your water change schedule keeps the nutrient levels low enough that you can avoid heavy algae growth,the photoperiod in the tropics is always 12 hours of light and 12 hours of darkness.
