Marlboro Yellow Discus 12cm

Discus are shy and generally peaceful aquarium inhabitants. They are sensitive to stress and disturbance or lack of protection. The best cohabitants may be angelfish and small characides like tetras. It is noteworthy, however, that small fish may be intimidated or eaten by the discus. Catfish with sucker mouths are less than ideal cohabitants for discus since they sometimes attach themselves on the sides of discus and eat their mucus membranes.

Many aquarists consider discus to be finicky and not particularly hardy. They often become susceptible to disease and die if not kept in optimal conditions.

Aquariums for discus should be kept within a temperature range of 26-31 C; a temperature of 29 C is thought ideal for adults. Babies and young fish should be maintained at 31 C degrees. The water should be very soft and acidic; a pH of 5.5 - 6.5 is considered good for wild caught discus.

Captive bred fish adapt very well to harder water and to pH up to 7.2, except when attempting to breed, in which case soft and acidic is best. VERY clean water with frequent large volume water changes is necessary for the health of these fish. Allow approximately 40 litres of water in the tank per each adult fish.

Water quality must be very high, as discus do not tolerate pollution of any sort very well. A good tank will be equipped with a high capacity biological filter and be fully cycled (which usually takes a month or more.) Ammonia and nitrites should be kept at 0 ppm. Nitrates should also be kept as low as possible. Weekly water changes are important, except in the case of a very heavily planted tank with high nitrogen compound grounding capacity and a very small biological load.

Feeding discus is sometimes a challenge. They have no unique nutritional requirements; they can be raised on just about any high-protein fish food. However, discus are often extremely cautious about new foods; it is not unusual for them to go for weeks without food before accepting a new type of food. After starving for a month discus will almost always accept a new food, but this may stunt the growth of younger fish.
