![]() ![]() This gently helps the fish getting used to higher lighting levels. Perfect for this are LED lighting systems, which can be continuously adjusted in brightness via a daylight simulator. Discus from local breeders in particular can, with a bit of patience and understanding, get used to stronger lighting. reddish stem plants, the lighting should be of the category “medium” to “high”. In order to keep more demanding plants e.g. To test if the lighting is sufficient, we recommend using the Flowgrow lighting calculator. If you want to keep more demanding plants, it is worth intensifying the aquarium lighting. Younglings in the rearing, which still need to grow to maturity, might need food up to five times a day. Discus fish are often fed several times a day, about two to three times. This is due to their relatively short digestive tract. This is necessary because discus fish eat quite a lot - and often - producing a corresponding amount of feces. For the removal of suspended solids, you won’t be able to do without mechanical filtration, or a sufficient biological filtration, which takes care of breaking down the pollutants caused by the organic water load. While a certain "less-is-more" approach to filtration with only a few filter media has established itself for typical aquascapes with just a few or tiny inhabitants, a discus aquarium needs much more intense filtration. A monitoring, by means of a pH-Controller is also useful.Īnother aspect in fusing a discus- with a planted aquarium is the overall filtration. In any case, the CO 2 concentration needs to be monitored using a drop checker. ![]() Lower values of 15 to 20 mg/l are quite acceptable for sufficiently supplying your plants. The recommended reference values of 20 to 30 mg/l CO 2 should not be the top priority, but the health and well-being of the fish. CO 2Ĭarbon fertilization is a bit of an issue when keeping discus, because they are pretty allergic to high CO 2 levels. Higher temperatures close to 30° are too much for most plants, which drastically limits your choices. As a compromise between the keeping of fish and plants, a temperature of 28° can be realized pretty well. Most plants in our shop have a rundown of their planting and cultivation conditions available in their profile, including their temperature tolerance. Temperatureĭue to the higher keeping temperature, priority should be given to plants that can stomach this. For this purpose, we will cover the relevant topics individually. In fact, you have to make some compromises here and find a good middle ground to meet the demands of both the discus and plants. With a little patience and long periods of adjustment, the lighting intensity can be gradually increased so that even more sophisticated aquatic plants can be kept. Domestically bred fish usually are already used to more intense lighting. The introduction of floating plants helps keeping light levels low. The lighting should initially not be too strong, because discus, especially those captured in the wild, are rather light-sensitive. While hunting for food, discus like to blow through the substrate in order to reach the microorganisms living inside. ![]() As a substrate, fine sand is advisable at least in a couple of selected spots. This will serve the fish as hiding spots and shelters and together with the aquatic plants they’ll ensure a well-structured design of the aquarium layout. The aquarium should be decorated with a lot of roots and driftwood, just as in their natural habitats. Instead of purchasing a high-power heater, it is a better idea to install two smaller heaters at the opposing ends of the tank, providing a better heat distribution and also the water temperature won’t sink too quickly should one of the heaters fail. Relevant literature states the ideal keeping temperature at a rather high 27 to 30☌. As a rule of thumb you should plan with 50 to 80 liters per animal. Discus are schooling fish and should be kept in groups of 5 animals upwards in a correspondingly large aquarium. Apart from some aquatic plants, mostly deadwood as well as tree branches and the roots of surrounding trees and bushes can be found in the waters of their natural habitats.ĭiscus prefer low pH and soft water, just like most aquatic plants and other ornamental fish from South America. Discus fish are native to the Amazon region of South America, where temperatures are higher, especially in the larger water streams. Their high-backed and compact physique is reminiscent of a discus or frisbee, which is what got them their nickname. They belong to the family of cichlids, even though their unique, round shape isn’t exactly a dead giveaway. ![]() Discus, popularly called the kings of the aquarium, are really particular animals, which stand out for their majestic grace and color. ![]()
