Full Care Guide
Discus Fish Care: Tank, Water & Group Guide
Discus are social Amazonian cichlids with specialised aquarium needs. OATA advises at least five fish, except an established breeding pair, and about 50 litres per adult—roughly 300 litres for six adults. Use that as a planning floor, then check usable dimensions, filtration, source water and the actual fish.

Among the red discus lines, Red Pearl stands apart — a warm red strain whose name nods to a pearl-style pattern, carried on the unmistakable disc-shaped body that makes Symphysodon the king of the softwater aquarium. Positioned mid-tank as the record describes, it reads as a moving splash of red at the heart of the display.
The husbandry brief is demanding but precise. This strain wants 26–30 °C, a pH between 5.0 and 7.0, and notably soft water — the record caps hardness at just 9 dGH, a touch tighter than many discus listings. Give it no less than 250 litres. Do that consistently and you are rewarded with a fish that grows to around 18 cm and, with Expert-standard care, can live a full decade.
As an omnivore, the Red Pearl accepts a broad, varied diet rather than demanding a specialist menu. Its peaceful character suits a carefully chosen community: fellow calm discus, cardinal and rummy-nose tetras, Corydoras catfish, Otocinclus and peaceful dwarf cichlids are all on the approved list, while aggressive cichlids, fin-nipping barbs, large predators, fast boisterous community fish, coldwater species and hard-water livebearers are firmly off it.
Why the fuss about hardness? Because 9 dGH is the ceiling on this particular record, and water harder than that works against everything else you do for the fish. If you keep other discus already, measure rather than assume — this strain's tolerance is narrower than some of its tank-bred cousins. Acclimatisation questions, breeding notes and feeding specifics are all addressed in the FAQ section below the listing.
