Leopard Discus (Symphysodon leopard) 7cm (9cm)

Overview

The Leopard Discus (Symphysodon leopard) is a highly sought-after ornamental cichlid admired for its elegant disc shape, calm demeanour and distinctive spotted patterning. Offered here at around 7cm (with some variation to 9cm), these are young fish with excellent potential to develop into impressive adults under the right conditions. Discus are often considered the jewel of the freshwater aquarium, and the leopard form is especially popular for aquarists who want a bold, natural-looking pattern with the classic discus silhouette.

Discus are not a beginner fish in the strictest sense, but they are very rewarding for keepers who can provide stable, warm, clean water and a peaceful environment. They thrive in mature aquariums with excellent filtration, regular maintenance and a carefully chosen community. At Tropical Fish Co, we select healthy stock and offer fast UK delivery alongside our live arrival guarantee, so your fish arrive in the best possible condition for acclimation.

As with all discus, the key to success is consistency. Stable temperature, low stress, and high water quality are more important than elaborate décor. Once settled, Leopard Discus can become confident, responsive fish that feed well and display superb colour and pattern.

Care at a Glance

Origin & Natural Habitat

Discus originate from the Amazon basin in South America, where they inhabit slow-moving floodplain waters, quiet backwaters and forested tributaries. In the wild, they are typically found in warm, shaded environments with soft, acidic water and abundant submerged roots, leaf litter and marginal vegetation. These habitats are often low in mineral content and rich in tannins, which help create the gentle conditions discus are adapted to.

The leopard pattern seen in aquarium strains has been developed through selective breeding, but the fish still retain the same biological needs as wild discus: warm water, low stress, and pristine conditions. Their laterally compressed body shape and social behaviour are well suited to calm, slow-flowing waters where they can move in loose groups and feed on small invertebrates, plant material and detritus.

Tank Setup & Water Parameters

For Leopard Discus, stability is everything. A mature aquarium of at least 250 litres is recommended for a small group, with larger tanks being preferable if you plan to keep a proper discus community. Tall tanks are often favoured because discus appreciate vertical swimming space and look especially impressive in a well-planted display.

Use a powerful but gentle filtration system to maintain excellent water quality without creating excessive current. Discus dislike strong, turbulent flow, so aim for a calm circulation pattern. A heater with reliable thermostat control is essential, as these fish should be kept warm year-round at 25–29°C. Sudden temperature swings can cause stress and suppress feeding.

Water should be soft to moderately hard, with a pH ideally between 6.0 and 7.5. While captive-bred discus can adapt to a slightly wider range than wild fish, they still do best when kept in clean, stable water with low nitrate. Regular partial water changes are vital, especially in heavily stocked or feeding-intensive setups. Many successful keepers change 25–50% several times per week, depending on stocking and filtration.

Décor should support calm behaviour and reduce stress. Driftwood, broad-leaved plants, smooth stones and open swimming areas work well. Dim lighting or floating plants can help discus feel secure. If using substrate, choose a fine, smooth material that is easy to clean. Avoid sharp ornaments and anything that could damage their delicate fins or body.

Because discus are sensitive to poor water quality, it is best to add them only to fully cycled, mature aquariums. New tanks are not suitable. A quarantine period is also strongly recommended for any new fish, especially in premium discus systems.

Feeding Guide

Leopard Discus are omnivorous and should be offered a varied, high-quality diet. A good discus staple may include specialist discus granules, soft sinking pellets, frozen foods such as bloodworm, mysis, brine shrimp and daphnia, plus occasional live foods from reputable sources. Many keepers also use beef heart-based discus foods, though these should be fed sensibly as part of a balanced regime rather than as the sole diet.

Young discus, including fish at this size, benefit from frequent small meals to support growth and development. Feed two to four times daily in modest portions, ensuring all food is eaten promptly. Overfeeding can quickly degrade water quality, so remove uneaten food and maintain strong husbandry. A varied diet helps bring out colour, supports immune health and encourages steady growth.

It is wise to observe feeding behaviour closely. Healthy discus are confident feeders once settled, but new arrivals may need a quiet environment and a little patience before they begin eating well. Offering a mix of soft, palatable foods can help with acclimation.

Tank Mates / Compatibility

Leopard Discus are peaceful fish and should be housed with calm, non-nippy species that enjoy similar warm water. Good companions include cardinal tetras, rummy nose tetras, pencilfish, Corydoras sterbai, peaceful dwarf cichlids from suitable water conditions, and other gentle Amazonian species. In larger aquariums, carefully selected peaceful catfish and small schooling fish can also work well.

Avoid boisterous, aggressive or fin-nipping fish, as well as species that prefer cooler water or hard, alkaline conditions. Fast feeders can outcompete discus at mealtimes, and overly active tank mates may cause stress. Discus are best kept in a thoughtfully planned community or a species-focused setup where their needs take priority.

When keeping a group, social structure matters. Discus are naturally social and often do best in groups, which helps reduce shyness and encourages more natural behaviour. However, ensure the tank is large enough to prevent bullying and to give subordinate fish space to retreat.
