A sharp drop in water temperature is extremely stressful to fish and can compromise their immune system. Improperly sized heaters may not be able to maintain their set temperature and cause aquarium temperature to fluctuate several degrees per day.
Temperature can be the single most important component in the life of your fish. Fish, in the wild and in our aquariums, are very sensitive to changes in temperature. Learn the affects of water temperature on fish health.
