Tank Setup for Discus Fish

Discus Fish Care Guide Feeding,Breeding Tips

Creating an optimal environment for Discus Fish involves careful attention to their specific needs. Here’s a comprehensive guide to setting up a tank that will keep your Discus healthy and thriving.

Tank Size and Water Parameters

Discus Fish require a spacious tank to accommodate their size and swimming habits. A minimum of 50 gallons is recommended for a small group of Discus. Maintain water temperatures between 82-86°F (28-30°C) to replicate their natural tropical environment. The pH level should be slightly acidic to neutral, ideally between 6.0 and 7.0, with soft to moderately hard water (1-8 dGH).

Filtration and Water Quality

A high-quality filtration system is crucial to keep the water clean and free of toxins. Discus Fish are sensitive to water quality, so it’s essential to use a filter that provides both mechanical and biological filtration. Ensure the filter creates a gentle flow, as strong currents can stress the fish.

Substrate and Decorations

Use a fine, soft substrate such as sand or smooth gravel to create a comfortable environment for Discus Fish. Include plenty of decorations like driftwood and rocks to provide hiding spots and reduce stress. Live plants such as Amazon Swords, Java Fern, and Anubias can enhance the tank’s aesthetics and offer additional cover.


Moderate lighting is best for Discus Fish. They thrive in well-lit environments but can become stressed under overly bright lights. Using adjustable lighting or adding floating plants can help diffuse the light and create a more comfortable setting.


Regular maintenance is key to keeping Discus Fish healthy. Perform weekly water changes of 25-30% to maintain water quality and reduce the buildup of harmful substances. Use a gravel vacuum to clean the substrate and remove any uneaten food or waste.


Discus Fish require a varied and nutritious diet. Feed them high-quality flakes or pellets specifically formulated for Discus, supplemented with live or frozen foods like brine shrimp, bloodworms, and daphnia. Regular feeding of vegetables such as spinach or peas can also be beneficial.

How to Feeding Discus Fish? 

Feeding discus fish properly is essential for their health and vibrant colors. Here’s a straightforward guide:

Variety of Foods: Offer a mix of high-quality flake food, pellets, frozen, and live foods like bloodworms, brine shrimp, and beef heart to ensure a balanced diet.

Frequency: Feed adult discus 2-3 times a day. Juveniles should be fed 3-5 times a day to support their growth.

Portion Size: Provide only what they can consume within 5-10 minutes to avoid overfeeding and water quality issues.

Supplements: Occasionally add vitamins and minerals to their food to enhance their immune system and color.

Clean Up: Remove uneaten food after 30 minutes to prevent contamination and maintain water quality.

Consistency: Maintain a regular feeding schedule to reduce stress and promote healthy eating habits.

    How to Breeding Discus Fish?

    Group of Discus Fish

    Breeding discus fish can be rewarding but requires specific conditions and care. Here’s a concise guide:

    Pair Selection: Choose a healthy, mature pair (12-18 months old). Observe their behavior to identify natural pairs or purchase an already bonded pair.

    Breeding Tank Setup:

    • Size: Minimum 20-gallon tank.
    • Temperature: Maintain at 82-86°F.
    • pH: Keep between 6.0-6.5.
    • Water Quality: Soft water (1-4 dGH). Regular water changes are crucial.

    Tank Environment:

    • Use a sponge filter to ensure gentle water flow.
    • Provide flat surfaces (e.g., a breeding cone or flat rock) for egg laying.
    • Keep the tank bare-bottomed for easy cleaning.

    Conditioning: Feed the pair a high-protein diet (live and frozen foods like bloodworms and brine shrimp) to condition them for breeding.


    • The female will lay eggs on the chosen surface.
    • The male will follow to fertilize the eggs.
    • Eggs will hatch in about 48-60 hours.

    Parental Care:

    • Parents will fan the eggs and keep them clean.
    • Once hatched, fry will feed off the parents’ mucus for the first few days.

    Raising Fry:

    • After a week, start feeding the fry baby brine shrimp.
    • Gradually introduce finely crushed flake food as they grow.

    Monitoring: Keep a close eye on water quality and health of both parents and fry. Perform regular water changes to maintain optimal conditions.

      Discus fish grow at a moderate rate. With proper care, diet, and optimal water conditions, they can reach adult size within 1-2 years. Juveniles should be fed frequently to support their growth.

      7. Can discus survive alone? 

      Discus fish are social creatures and prefer to live in groups. While they can survive alone, they may become stressed and exhibit less vibrant colors and reduced activity. It is best to keep them in groups of at least 5-6 for their well-being.
