You can exclude this risk. Water temperatures and influence on fish behaviour Normal temperatures for keeping discus fish lie at 29-30 Â°C. If your fish are too calm and do not eat greedily but are hesitant about eating, raise the water temperature for c. two weeks to 33 Â°C. This will raise the metabolic rate of the discus fish and encourage their appetite and their sense of hunger.
