How to Care for Discus in an Aquarium
Discus are not only beautiful, but also intelligent and social fish that can form strong bonds with their owners and tank mates. However, they also have some special requirements that need to be met in order to keep them healthy and happy. Here are some tips on how to care for discus in an aquarium:
Choose a suitable tank size and filtration system. Discus need a large and tall tank with plenty of swimming space and gentle water movement. A general rule is to provide at least 10 gallons of water per discus. A canister filter or a sump filter can provide adequate filtration and water circulation for a discus tank. Make sure to clean the filter regularly and avoid overstocking the tank.
Maintain optimal water parameters and quality. Discus prefer warm, soft, and acidic water with a pH between 6 and 7 and a temperature between 82 and 90 degrees F. They are sensitive to ammonia, nitrite, and nitrate, so make sure to cycle the tank before adding them and perform weekly water changes of at least 25%. Use dechlorinated or reverse osmosis water with water conditioner and test the water regularly with a test kit.
Provide a suitable diet and feeding schedule. Discus are omnivorous fish that need a varied diet of high-quality foods. You can feed them flakes, pellets, frozen or live foods, such as bloodworms, brine shrimp, beef heart, or blackworms. Feed them no more than 3% of their body weight per day, divided into 2-3 feedings. Avoid overfeeding or underfeeding your discus, as this can cause health problems.
Add some plants and decorations. Discus like to have some cover and hiding places in their tank, as well as some vertical elements that mimic their natural habitat. You can add some live or artificial plants, driftwood, rocks, or ornaments to create a natural-looking and comfortable environment for your discus. However, avoid sharp or rough objects that can injure your discus or clutter the tank too much.
Select compatible tank mates. Discus are peaceful and social fish that do best in groups of at least six. They can also get along with other calm and non-aggressive fish that can tolerate the same water conditions and temperature. Some good tank mates for discus are cardinal tetras, rummy nose tetras, corydoras catfish, angelfish, rams, or plecos. Avoid keeping discus with fin-nippers, aggressive fish, or fish that require cooler water.
By following these tips, you can enjoy keeping discus in your aquarium and admire their beauty and personality. Discus are rewarding fish that can bring you joy for many years if you take good care of them. 061ffe29dd
