You probably put on a sweater or turn up the thermostat. So in your home aquarium, the goal is to maintain a water temperature that is within the preferred range of your fish, invertebrates, plants or corals. It is this rapid change in temperature that is the problem. The small amount of water can quickly heat up or cool down based on the temperature outside the tank. Your aquarium, on the other hand, is not so lucky. The change in temperature can take a day or even a season to complete. Well, it all comes down to how fast the aquarium temperature swings.īecause oceans and rivers contain so much water, it takes a long time for the temperature to rise or drop. So if this is the case, then why do we insist on keeping our aquariums at a constant and stable temperature? Even in the reef environment, the daily temperature swings from 68-90☏ (20-32☌). In fact, freshwater fish can experience daily temperature swings of 30☏ or more. Rain, hot summer days and cold winter nights all work together to ensure that fish in their natural environment do not experience the same temperature for too long. This makes sense, I mean, in the wild, there is no aquarium heater ensuring that the water temperature remains constant.
