Do Discus Fish Need A Heater?

Discus needs an aquarium heater to stay alive, unlike Mammals, Discus fishes do not have the ability to regulate their own body temperatures. They are dependent on their environment to regulate their body temperature.

These tropical fishes need the Discus aquarium heater for three main reasons:

  • To maintain and stabilize the temperature range of the aquarium.
  • To increase metabolic activities in the body of the fish.
  • To keep disease-causing pathogens away from the aquarium tank etc.

With the right Discus tank heater and temperature, your Discus will hardly bloat.
