Discus fish are known for their vibrant colours and unique, round body shape. They are a popular choice for aquarium enthusiasts who want to add a touch of elegance and beauty to their tank. Setting up a Discus tank requires attention to detail, as these fish have specific needs that differ from other freshwater species.
Step 1: Choose the right tank size
Discus fish require more space than most other freshwater fish due to their size and territorial nature. You will need a minimum tank size of 40L (10 gallons) per adult Discus. The tank should be at least 45 cm (18 inches) tall, as Discus prefer deeper water to swim in. If you plan to keep more than six Discus, consider a larger tank to accommodate their needs.
Step 2: Ensure optimal water conditions
Discus fish thrive in specific water conditions, which differ from those of other tropical fish. The ideal water temperature for Discus is 28-30°C (82-86°F). Use a reliable aquarium heater and a thermometer to maintain a consistent temperature.
The water’s pH should be between 6.0 and 7.0, with a hardness of 1-4 dH. If you live in an area where the tap water doesn’t align with these parameters, this soft, acidic water environment can be achieved by using reverse osmosis water or adding peat moss to the filter. Regularly test the water parameters using a water testing kit to ensure stability.
Step 3: Install proper filtration
Discus fish are sensitive to water quality, so a high-quality filtration system is essential. A canister filter or a power filter with a bio-wheel is ideal for a Discus tank. The filter should be powerful enough to turn over the tank’s water volume at least 5-6 times per hour. Regular maintenance of the filter is crucial to prevent ammonia and nitrite build-up, which can be harmful to Discus.

Step 4: Create a comfortable environment
Discus fish prefer a low-light environment with plenty of hiding spots. Use floating plants or tall plants near the tank’s sides to create shade and cover. Driftwood, rocks, and caves can also be added to create hiding spots and territories for your Discus.
A dark-coloured substrate, such as black sand or fine gravel, will help bring out the vibrant colours of your Discus. The substrate should be 5-7 cm (2-3 inches) deep to allow for proper planting and to create a natural look.
Step 5: Introduce suitable tank mates
While Discus can be kept in a species-only tank, they can also coexist with other peaceful, slow-moving fish that share similar water parameter requirements. Suitable tank mates include cardinal tetras, rummy-nose tetras, and corydoras catfish. Avoid aggressive or fast-moving fish, as they may stress your Discus and lead to health issues.

Step 6: Acclimate and introduce your Discus
Before introducing your Discus to the tank, allow them to acclimate to the water conditions.
Fill a bucket with water from your tank and add an air stone and Melafix Pond to the bucket. Transfer your new fish into the bucket and allow it to sit for 20 minutes. Transfer your fish to your aquarium and add Melafix Pond to your aquarium. Monitor your fish and complete a 50%+ water change the following day.
This gradual process will help reduce stress on the fish and prevent potential health problems.

Step 7: Maintain a proper diet and feeding schedule
Discus fish require a high-protein diet to maintain their vibrant colours and overall health. Feed them a variety of high-quality pellets, flakes, frozen, and live foods. Offer your adult Discus meals 1-2 times per day and remove any uneaten food after 5 minutes to prevent water quality issues.
