It needs sophisticated care including stable water conditions and low ammonia/nitrates. The Diamond Discus will become noticeably more protective during spawning and thus require a large aquarium where they can have their own space. Blue Discus are peaceful and will form families, especially with direct siblings. Blue Diamond Discus are best purchased in schools of the same size. Adding them to the aquarium at the same time will avoid conflict and allow them to develop their own territories.
