Turquoise Checkerboard Discus (Symphysodon sp.) 7cm (9cm)

Overview

The Turquoise Checkerboard Discus is one of the most admired freshwater aquarium fish, prized for its elegant shape, calm nature and striking turquoise patterning. Offered at around 7cm (9cm), these young discus are a superb choice for aquarists looking to grow and condition a show-quality centrepiece fish. Their rounded body, flowing fins and intricate checkerboard markings make them a true focal point in any carefully maintained aquarium.

Discus are not a beginner fish, but in the right environment they reward the keeper with exceptional colour, graceful behaviour and fascinating social interactions. They thrive in warm, clean, stable water and appreciate a peaceful aquarium with plenty of space. At Tropical Fish Co, we supply healthy livestock with a live arrival guarantee and fast UK delivery, so your new discus can settle in with the best possible start.

As with all discus, success comes from consistency. A mature tank, excellent filtration, regular water changes and a varied diet are key to long-term health. If you can provide those essentials, the Turquoise Checkerboard Discus can become one of the most rewarding fish in the hobby.

Care at a Glance

Origin & Natural Habitat

Discus originate from the slow-moving blackwater and clearwater systems of the Amazon basin in South America, where they inhabit flooded forests, calm tributaries and sheltered margins with dense vegetation and submerged wood. In nature, these waters are typically warm, soft and acidic, with very low mineral content and excellent seasonal stability. The fish are adapted to living in groups, often among roots and leaf litter where they can find shelter and forage for small invertebrates, plant matter and biofilm.

The Turquoise Checkerboard Discus is a selectively bred aquarium form derived from Symphysodon species, developed to enhance the vivid turquoise sheen and patterned body markings that make discus so distinctive. While captive-bred strains are more adaptable than wild-caught fish, they still retain the same need for pristine water quality, warmth and low stress. Understanding their natural environment is the best way to provide successful long-term care in the aquarium.

Tank Setup & Water Parameters

For best results, keep Turquoise Checkerboard Discus in a spacious, mature aquarium of at least 250 litres, with larger tanks strongly recommended for groups. Discus are social fish and do best when kept in a small shoal of five or more, which helps reduce stress and encourages natural behaviour. A tall or wide tank with open swimming space and some shelter from driftwood, broad-leaved plants and smooth décor is ideal.

Water quality is absolutely critical. Maintain a temperature between 26 and 30°C, with 28°C often a good everyday target. Aim for a pH between 5.0 and 7.0, and keep hardness low to moderate, ideally below 10 dGH. Stable conditions are more important than chasing exact numbers, so avoid sudden changes in temperature, pH or chemistry. Efficient filtration is essential, but the flow should not be excessive; discus prefer gentle circulation and calm water movement.

Regular maintenance is non-negotiable. Weekly water changes of 30–50% are common in discus keeping, especially in heavily stocked or growing tanks. Use a reliable heater and thermometer, and ensure the aquarium is fully cycled before adding fish. Fine sand or a smooth bare-bottom setup can work well, depending on your maintenance style. Live plants such as Amazon swords, Vallisneria and Anubias can help create a natural look, but choose species that tolerate warm water.

Because discus are sensitive to poor water conditions, they are best kept in established aquariums rather than newly set-up tanks. Quarantine new fish where possible, and introduce tank mates carefully. A calm environment, subdued lighting and consistent feeding routines will help your discus settle and thrive.

Feeding Guide

Turquoise Checkerboard Discus are omnivores with a strong preference for rich, high-quality foods. Offer a varied diet built around premium discus pellets or granules, supplemented with frozen foods such as bloodworm, mysis, brine shrimp and daphnia. Many keepers also use specialised beefheart-style discus foods, though these should be fed sensibly as part of a balanced rotation rather than as the sole diet.

Young discus benefit from frequent small meals, often three to five times daily, to support steady growth. Adults can be fed two to three times per day depending on stocking and filtration. Feed only what they will consume promptly, and remove excess food to protect water quality. Variety is important for colour, growth and immune health, so rotate between prepared, frozen and occasional live foods where appropriate.

Because discus are slow, deliberate feeders, make sure they are not outcompeted by faster tank mates. If necessary, target feed them to ensure each fish receives enough nutrition. A well-fed discus is more likely to show strong colour, confident behaviour and good body condition.

Tank Mates / Compatibility

Discus are peaceful fish and should be housed with other calm species that enjoy similar warm, soft-water conditions. Good companions include cardinal tetras, rummy nose tetras, pencilfish, Corydoras sterbai, German blue rams, peaceful dwarf cichlids and certain small loricariids such as bristlenose plecs, provided the tank is large enough and water quality remains excellent. In general, choose fish that will not nip fins, race around the tank or dominate feeding time.

Avoid boisterous, aggressive or nippy species, including tiger barbs, many larger barbs, common plecs in smaller tanks, fast danios, and most semi-aggressive cichlids. Goldfish, livebearers and hard-water species are also poor matches because their environmental needs differ significantly. Discus are best kept in a species-focused or carefully planned community aquarium where all inhabitants share similar requirements.

When selecting tank mates, remember that discus prefer warmth and stability. Any companion fish must tolerate temperatures around 28°C and should not produce excessive waste. Overcrowding should be avoided, as it can quickly lead to stress and water quality issues.
