Can a flowerhorn cichlid be housed with discus?

Housing flowerhorn cichlids with discus is generally not recommended due to differences in temperament and care requirements. Flowerhorns are aggressive and territorial, which can stress out the more peaceful and sensitive discus. Additionally, flowerhorns prefer a higher pH and temperature range, while discus thrive in softer, more acidic water. For the health and well-being of both species, it's best to keep them in separate tanks.
