!With conditions
  • Only a narrow temperature range suits both: exactly 26 °C.
!With conditions
  • Rift lake cichlids like electric yellow cichlid need hard, alkaline water and a busy, cichlid-only tank.
  • Their pH needs don't quite meet (6–7.5 vs 7.7–8.6). Aim between the two and keep it steady.

Behavior

Semi-aggressive with its own kind; best alone or with large fish.

Not for home aquariums. This fish grows far too big for any home tank. It needs a pond-sized system of thousands of litres, so please don't buy one as a baby.

Food

Vegetables and spirulina.

The story of the six-barred distichodus

A big Congo-basin characin that can reach about 75 cm. Juveniles are orange with dark bars and bright red fins, but much of this colour fades with age. It eats plants as well as worms, crustaceans and insects, so it destroys most planted tanks.

George Albert Boulenger described this fish in 1897 from the Congo basin. Young fish are bright orange with six dark bars, which made them popular in shops, but the colours fade as they grow. Adults become large plant-eaters that can reach around 75 cm.

First described by George A. Boulenger in 1897. Named for 'sexfasciatus' means six-banded.

  • Young fish are bright orange with six dark bars.
  • Adults fade and lose much of their bright colour.
  • It readily eats aquarium plants.

15 facts checked with sources

  • Scientific name

    Described by Boulenger, 1897. D. tanganicae is a synonym. Juveniles are easily confused with D. lusosso, which has a long pointed snout.

    Eschmeyer's Catalog of Fishes: Distichodus sexfasciatus · FishBase: Distichodus sexfasciatus summary
  • Familycorrected

    Legacy has no family. Seriously Fish still files it under Citharinidae (older, broader grouping); Catalog of Fishes and FishBase use Distichodontidae.

    Eschmeyer's Catalog of Fishes: Distichodus sexfasciatus · FishBase: Distichodus sexfasciatus summary · Seriously Fish: Distichodus sexfasciatus
  • Size

    FishBase 76 cm SL, Seriously Fish 75 cm SL (standard length); legacy 75 agrees within rounding. Aquarium specimens rarely exceed ~40 cm.

    FishBase: Distichodus sexfasciatus summary · Seriously Fish: Distichodus sexfasciatus
  • Temperaturecorrected

    Both sources 22-26; legacy 24-28 runs warmer.

  • Smallest tankcorrected

    240 x 90 x 60 cm = 1,296,000 cm³ = 1,296 L for a single fish (Seriously Fish). Legacy 1,200 L is slightly under.

    Seriously Fish: Distichodus sexfasciatus
  • Group size

    Usually kept singly. FishBase says wild fish swim in shoals, so a group needs an enormous tank.

    Seriously Fish: Distichodus sexfasciatus
  • Temperament

    Do not keep with much smaller or shy fish.

    Seriously Fish: Distichodus sexfasciatus
  • Swimming levelcorrected

    Legacy "middle"; both sources put it low in the water.

    Seriously Fish: Distichodus sexfasciatus · FishBase: Distichodus sexfasciatus summary
  • Care levelcorrected

    Difficulty comes from its size, not fragility. Legacy 2 (moderate) too low.

    Seriously Fish: Distichodus sexfasciatus
  • Where it livescorrected

    Legacy has no range field. Seriously Fish lists "Cameroon, Democratic Republic of Congo, Tanzania"; Cameroon is not supported by Catalog of Fishes or FishBase.

    Eschmeyer's Catalog of Fishes: Distichodus sexfasciatus · FishBase: Distichodus sexfasciatus summary
  • Male or female

    Seriously Fish lists sexual dimorphism as "Unknown", consistent with legacy "no visible difference".

    Seriously Fish: Distichodus sexfasciatus
  • Breeding

    Legacy "Not bred in aquaria" verified. The legacy spawning-tank recipe (school of 6+, rainy-season water changes, mops) is speculative and unsourced.

    Seriously Fish: Distichodus sexfasciatus
  • Storycorrected

    Legacy calls it a herbivore; sources describe an omnivore that eats a lot of plant matter. Legacy red fins and six bars describe juveniles; adults lose much of the colour. Often wrongly sold as a community fish (Seriously Fish).
