Discus
Discus belong to the genus Symphysodon, which currently includes three species: The common discus (Symphysodon aequifasciatus), the Heckel discus (Symphysodon discus), and a new species which has been named Symphysodon tarzoo.
Discus are shy and generally peaceful aquarium inhabitants. They are sensitive to stress and disturbance or lack of protection. Therefore, it is best to keep discus aquariums in quiet, low traffic areas of a home or office, and to provide the fish with plenty of hiding places. Many aquarists consider discus to be finicky and are not recommended for inexperienced aquarists. Discus are not particularly hardy and they often become susceptible to disease and die if not kept in optimal conditions. Ammonia (produced from fish waste) and suboptimal water temperatures are the biggest threats to the immune system of a discus. In their natural habitat, discus live in essentially distilled water, therefore, the chemicals commonly added to the municipal water supply can be dangerous to the fish. It is for this reason that many discus enthusiasts ultimately choose to do water changes using RO water.
Aquariums for discus should be kept within a temperature range of 26-31 C; a temperature of 29 C (84 F) is thought ideal for adults. Babies and young fish should be maintained at 31 C (88 F) degrees. The water should be very soft and slightly acidic; a PH of 5.5 – 6.5 is considered good for discus.
