Discus are often called the “king of the aquarium” because of their elegant shape, calm presence and premium appearance. This species is best suited to a mature, warm, peaceful aquarium with excellent water quality, soft acidic conditions and calm tank mates. While peaceful by nature, discus are specialist fish and should be kept by aquarists who can maintain stable, high-quality water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003eBlue Discus.

In nature, discus are associated with warm, slow-moving waters, submerged roots, fallen branches, flooded forest areas and soft acidic blackwater environments. Most blue discus available in the aquarium trade are captive-bred colour strains rather than wild fish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater Parameters:\u003c\/strong\u003e\u003cbr\u003eTemperature: 27–30°C\u003cbr\u003epH Range: 5.5–7.0\u003cbr\u003eHardness: soft water preferred, ideally low to moderate hardness\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e\u003cbr\u003ePeaceful but specialist. Discus are calm cichlids that should be kept with gentle tank mates that will not bully them, nip fins or outcompete them for food. Avoid aggressive, fast-moving or boisterous fish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e\u003cbr\u003eOmnivorous with a preference for small animal-based foods. It should be offered a varied diet including quality discus granules, soft pellets, frozen bloodworm, brineshrimp, mysis, daphnia, blackworm where suitable, and specialist discus foods.

A 120 cm aquarium or larger is strongly recommended, as discus need swimming space, stable water volume and room to establish a social hierarchy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBehaviour \u0026amp; Activity:\u003c\/strong\u003e\u003cbr\u003eThis is a calm mid-water cichlid that should usually be kept in a group of at least 5–6 individuals unless maintaining a proven breeding pair. In groups, discus are more confident and display more natural behaviour, but they can still form hierarchies. They appreciate tall aquariums, gentle flow, shaded areas, wood, plants and open swimming space. Sudden movement, unstable water or aggressive tank mates can cause stress.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAquarium Category:\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003eCommunity Fish\u003c\/span\u003e\u003cbr\u003eThis species is peaceful enough for a carefully planned specialist community aquarium.

Regular maintenance, excellent filtration, low nitrate and careful feeding are essential. They should not be added to immature aquariums or unstable systems. Captive-bred discus are generally more adaptable than wild discus, but they still need consistency and low stress. If keeping true Symphysodon discus \/ Heckel-type discus, softer, more acidic water and expert-level care may be required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e\u003cbr\u003eIntermediate to experienced fishkeepers\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e\u003cbr\u003eCommon \/ occasional in trade as captive-bred blue strains; true wild Symphysodon discus forms are rarer and more specialist.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAll images are a visual representation of the fish you will receive, made to be as accurate as possible.
