What water temperature should be maintained for keeping discus fish?

The ideal water temperature for keeping discus fish is 25-30 degrees C, and the temperature should be kept constant with minimal fluctuation. Within this range discus fish have a relatively strong appetite, while water that is too hot or too cold will affect their feeding.

Discus fish are omnivorous and prefer fresh animal-based food. Owners can usually feed them chopped beef, lean meat, chicken heart, fish and shrimp meat, mealworms, and yellow mealworms, as well as pellet feed.
