Guppies, on the other hand, prefer temperatures ranging from 76 to 78 Degrees F. hence, both species are hardy enough to survive in waters that are either cooler or warmer than their ideal temperatures.

NOTE: The consequences are rarely pleasant. If you raise the temperature to suit the Discus, you are going to reduce the lifespan of your guppies.

Guppies and Discus are both equally attractive creatures. However, that shouldn’t automatically compel you to place them in the same tank. Admittedly, it has been done on numerous occasions. But if you are dealing with one or both fish for the first time, you must take some factors into account. You need to have a tank of at least 50 gallons.

NOTE: I highly recommend purchasing a 55 gallons aquarium, it’s an all in one affordable tank for your new Discus hobby, check it out at Amazon 55-Gallon Starter Aquarium with Net, Food, Filter, Heater/Conditioner.
