The water temperature of a Discuss fish tank should be 82-88°F (27.77-31.11 °C)
The pH level of the water in the aquarium should be 6-7.
Discus fish lives in the combination of light acidic and slight soft water, so the water hardness should be 1-4 dKH.
Hygiene management is the most important thing to keep fish healthy and happy. Clean the walls and corners of a fish tank with soft sponge and liquid soap that has a low chemical level. After scrubbing the objects and the walls of the tank, wash it out with aerated water. Once the tank is cleaned, wipe out the water droplets from the tank with the help of a soft cotton rag or a cloth.

It is suggested to use a spawning cone which is the ideal place for laying eggs. You can also place a tube of wire over the eggs so that the other fish breeds don’t consume the Discus eggs.
Moreover, some parents eat their eggs, so separate the eggs from the adult fish if you are encouraging breeding. Discus specifically lay eggs in monsoon, so maintain the temperature and hardness of the water accordingly.
