Care at a glance
The discus is called the king of the Amazon aquarium for a reason: majestic, colourful and with a social group life you rarely see in other fish. But the crown has its price, because this is a species for keepers whose basics are in order.
Discus demand impeccable, warm, soft water, and that means discipline: generous, regular water changes and a tank that has been running stably for months. Keep them in a group and pick tankmates that tolerate the same heat. Those who put in the effort get the most beautiful community tank imaginable in return.
