![]() ![]() Two captive variants (orange and solid turquoise)Ī molecular study in 2011 found five main groups, which generally matched previously recognized phenotypes. aequifasciatus remains to be determined if valid it is widespread but it might just be a color morph. discus, meanwhile, seem to hybridise frequently in the wild or have diverged recently, as they lack mitochondrial DNA lineage sorting but differ in color pattern and have dissimilar chromosomal translocation patterns. tarzoo was described in 1959 and applies to the red-spotted western population. ![]() Other species and subspecies have been proposed, but morphometric data (unlike in Pterophyllum, the freshwater angelfish) varies as much between individuals from one location as across the whole range of all discus fish species. haraldi, currently considered a synonym of S. tarzoo was not described in accordance with ICZN rules and thus should be considered invalid and replaced with S. A review published in 2007 largely came to the same result, but differed in nomenclature, as the species called S. tarzoo, based on a taxonomic review published in 2006. ![]() The fish are also prone to internal and external parasite infections such as gill flukes.Discus are fish from the genus Symphysodon, which currently includes the species S. Diseaseĭiscus fish are most vulnerable to common warm-water bacterial infections such as cotton wool and hole-in-the-head disease. A newly added fish that lies on its side is not ill or dying - this is a normal reaction to the change in water pressure between the container and the aquarium, and the fish will soon acclimatize.Ĭhange 10% to 25% of the discus fish tank water weekly to maintain good water quality. In larger tanks, powerheads (submersible pumps) are preferredĭiscus fish bought online can be added directly to a prepared tank. Water type: Soft, freshwater Tank size: Minimum 60 gallons (10 gallons per discus fish) Water temperature: 82–88☏ (28–31☌) Substrate: Sand, pebbles, rocks Tank setup: Plants, caves, driftwood Acidity: 6.0–7.0 pH Water hardness: 6–14 dGH Filter: Yes, discus fish produce a large amount of waste and stir up the substrate, so a sturdy filter is essential Plants: Yes, to circulate the water in the aquarium and ensure an adequate oxygen supply. The fish congregate close to fallen trees and branches near river banks in the wild, so in captivity, discus prefer stable environments. The discus fish inhabits the slow-moving rivers and lakes of the lowland Amazon basin. Captive discus fish have more vibrant colors when water parameters are well-maintained, even though the fish adapt better than wild species to water fluctuations.Īdvertisements Habitat and Tank Requirements This species is challenging to keep in a mixed-species tank due to the discus fish’s low pH, high mineral content, and warm temperature needs. The blue discus is native to the eastern Amazon basin, the green discus is native to the western Amazon basin, and the red discus is native to the Rio Negro area. The discus fish is native to the Amazon river in South America. Patterned hybrids exist in captivity Diet: Omnivore Temperament: Intelligent, peaceful, shy Minimum tank size: 10 gallons per fish, or over 55 gallons for a group of six fish Temperature: 82–88☏ (28–31☌) pH: 6.0–7.0 Hardness: Soft water, 2–8 dGH Care level: Challenging, requires a higher temperature than many other species Breeding: Mouthbrooders Origin tarzoo (green discus) Common names Discus fish, pompadour fish, king of the aquarium Distribution: Amazon river basin, South America Size: 4.6–8 inches Life expectancy: 10–15 years in captivity Color: Wild discus fish are red, blue, or green, and other colors.
