How to Keep a Pleco: Water Temperature Requirements

The pleco is suited to growing in water temperatures of 18 to 30°C. If the water temperature is below 18°C or above 30°C, it will affect the pleco by making it listless or cause other illnesses and even death. Therefore, in the cold winter, a heating rod should be added to the water for keeping the pleco, and in the hot summer, ice cubes need to be added to the water to cool it down, so as to ensure the water temperature is suitable.

This way, the pleco can adapt to the new water source and will not be caused to panic.
