Pompadour Fish
COMMON NAMES: Discus or PompadourFish.
SCIENTIFIC NAMES: Symphysodon discus, andS. aequifasciata, plus several subspecificnames.
DESIGNATION: Tropical.
GEOGRAPHICAL DISTRIBUTION: Amazon basin.
SIZE: Up to 15 cm (6 in) or slightly larger.
WATER PREFERENCES: Soft, slightly acid wateris essential for the long-term welfare of thisspecies. Temperature: 25-30°C (77-86°F) andeven higher.
DIET: Although some dried foods may betaken, the diet should consist predominantlyof livefoods, freeze-dried and deep-frozenfoods. Minced ox-heart is readily accepted butshould not be considered as the dominantdietary component.
BREEDING: Eggs are laid on a pre-cleanedvertical. or nearly vertical. surface. Eggs and fry are guarded by both parents which secretea nutrient-rich body mucus for the fry to feedon. This characteristic, formerly thought to beunique to Discus, is now known to be sharedby a few other species, e.g. the Uaru (Uaruamphiacanthoides), another Cichlid from theAmazon basin.
DESCRIPTION: Despite thenumber of Discus types which are available,these all belong to just two species: the first isSymphysodon disc., which is the 'true'Discus or Heckel. It can be distinguished fromall others because it has three main verticalbars on its body: one through the eye, onethrough the centre of the body and the finalone through the caudal (tail) fin base. The second species is S. aequifasciata, andthis has several subspecies: (i) S. a.aequifasciata, the Green Discus which,despite its name, has red spots on its body; (ii)S. a. axelrodi. the Common or Brown Discus,which has markings restricted to the gillcovers and head; and (iii)S. a. haraldi, theBlue Discus, with similar marks to those ofthe Brown but extending further back ontothe body.Ease of interbreeding between both speciesand the subspecies, allied to meticulousselection for various characteristics, hasresulted in a wide range of hybrids, some ofwhich are difficult to classify. Anyone contemplating keeping Discus should dedicate a great deal of time talking to specialists. The effort will yield rich rewards.Discus are best kept as a shoal in largeroomy tanks either on their own, or withother smaller, non-aggressive species that arenot too active. Good plant cover or otherforms of shelter, such as bogwood, will befound beneficial.
