Brilliant Turquoise Discus (Domestic Symphysodon Strain)

Brilliant Turquoise Discus combine a blue-green ground colour with red or rust-toned markings across a deep, rounded body. This domestic Symphysodon strain makes a striking focal point in a warm freshwater display, particularly once a settled group begins to show its individual patterns and behaviour.

This listing supplies one unsexed fish per quantity in the selected size option. Choose the size and number you need using the purchase selector. Two fish are not automatically a pair, and this listing does not promise a male, female, proven breeding pair or exact colour pattern. The gallery contains representative illustrations rather than photographs of the individuals available for dispatch.

Choosing the right size

A smaller juvenile offers the opportunity to watch its colour and body shape develop. A larger fish may show more pattern immediately, but should still be matched carefully to the size and feeding confidence of an existing group. Buying a larger size does not guarantee breeding maturity or a particular place in the group's hierarchy.

The size options are supplier grades rather than measurements taken immediately before packing. Some grades include two figures in brackets; the measurement convention is not confirmed, so contact us if the difference matters for your aquarium. “XL selection HQ” is also a supplier label, not a verified pedigree, show award or sex guarantee. The selector shows which grades are currently available.

A domestic colour strain

Brilliant Turquoise describes an aquarium colour strain. It does not identify a wild collection locality or a separate species. We use Symphysodon spp. because the supplier has not provided the lineage evidence needed to assign this stock more precisely.

Real fish vary in the balance of turquoise, blue, red and darker markings. Juveniles can look quite different from mature adults, while lighting, background and stress affect apparent colour. The illustrations help show the intended type but are not a promise that every fish will match a rendered image. A two-fish illustration does not change the quantity supplied.

Aquarium size and social planning

Plan for adults reaching about 20 cm across. For a managed group of at least five compatible discus, use a mature aquarium of 300 litres and around 120 cm in length or larger. Increase the space for more discus or companion species. Floor area, swimming room and opportunities to avoid a dominant fish matter alongside the stated water volume.

Discus form social hierarchies. A lone fish or a group that is too small can become stressed, and two randomly chosen fish may not settle together. A genuinely established breeding pair in a specialist setup is a different situation from buying two unsexed fish. If adding one fish to an existing group, consider its size, health and feeding confidence as carefully as its colour.

Leave open swimming space and arrange smooth wood or suitable plants to create calmer areas. Choose plants that tolerate the warm conditions, and keep access clear for removing waste. This is an advanced-care fish for someone comfortable with water testing, mature filtration and regular maintenance.

Water conditions and maintenance

For this stock, plan stable water at 26–29°C, pH 6.0–7.5 and general hardness of 4–12 dGH. These working ranges overlap the previous supplier guidance and OATA's general discus recommendations. Ask about the holding conditions before delivery and avoid sudden changes in temperature or water chemistry.

Ammonia and nitrite should remain at zero. Test regularly, remove uneaten food and keep nitrate low through a water-change routine suited to the aquarium's stocking and feeding. Replacement water should be conditioned and closely matched to the aquarium. Large maintenance tasks are easier and safer when the setup is designed for them from the start.

Keep filtration dependable without creating a current that prevents the fish feeding or resting. Check heaters and thermometers routinely. A visually clear aquarium can still have unsuitable water, so observation should complement testing rather than replace it.

Feeding and body condition

Use a complete discus granule or pellet of a suitable size as the staple, with appropriate frozen or live foods for variety. Offer small, measured portions and allow time to see whether every fish feeds. A quiet individual may lose condition if confident fish take all the food first.

Young fish usually benefit from several small meals spread through the day, with the amount adjusted to growth, body condition and water quality. Remove leftovers promptly. Consistent feeding and clean water matter more than attempting to intensify colour with a single food.

Compatible fish and new arrivals

Build the aquarium around the discus first. Any companion must suit the actual warm-water conditions and avoid fin nipping, harassment or excessive competition for food. Some calm tetras and selected warm-tolerant bottom dwellers can work in a sufficiently large system, but the exact species needs checking. “Tropical” alone is not enough to establish compatibility.

Prepare a mature, heated quarantine system for new arrivals where possible. Follow the delivery instructions promptly and observe breathing, appetite and body condition as the fish settle. Do not introduce a new fish into an established group simply because its colour looks right if its health or size makes the match unsuitable.

The selected option and basket show the current price and quantity. Check the delivery information for postcode coverage and dispatch arrangements, and the Live Arrival Guarantee terms for the current conditions. If a size label is unclear, ask before ordering so you can choose a fish suited to the group you already have.
