correct temperature for aquariums
A good range is 76Â° to 80Â°F (25Â° to 27Â°C). A few species need to be kept several degrees warmer, and some species require temperatures a few degrees cooler. A thermometer is vital. A stick-on type enables you to check the temperature whenever you look at the aquarium. For tropical fishes a reliable heater is necessary, at least during the colder months of the year.
