TEMPERATURE

An important parameter for aquatic life, the temperature regulates the growth of animals and plants and exerts an influence not only on oxygen levels but also on many other factors.

The use of a heating kit allows the water in an aquarium to be maintained at an almost constant temperature  The use of a heating kit allows the water in an aquarium to be maintained at an almost constant temperature.

Whereas mammals have a regulated and practically stable internal temperature, that of fish and other aquarium creatures varies according to the temperature of the water around them. They can survive only at certain temperatures and some species are more sensitive than others to variations in this parameter.

The temperatures of fresh tropical waters, ranging from 20 to 30°C, are characterized by less significant variations than those found in temperate regions. In some places the shade provided by the tropical forest cools the water, while in calm water the temperature goes up under the direct influence of the sunlight.

The mean temperature most often recommended for aquariums is 25°C, and variations of 1 or 2° are of little consequence. Fish are even capable of withstanding even more significant variations for brief periods (under 24 hours). On the other hand, their metabolism (i.e. their general bodily functioning) is in danger of serious disturbance over any longer periods, and sooner or later they may die. It must also be noted that excessively low temperatures sometimes favor the development of certain diseases.
