Care at a glance
Species-specific aquarium care
- Tank: At least 180 in long and 60 in front to back for one adult (adults commonly reach about 29.9 in / 76 cm).
- Water: Freshwater.
- Temperature: 72–79°F (range recorded for this species).
- pH: 6–7.5.
- Hardness: 10–20 dGH.
- Layout: An open-water swimmer: needs long, open swimming space with few obstacles.
- Diet: Eats a varied diet: mix quality prepared foods with frozen and live foods. FishBase classes it as a omnivore.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 94 × 35 in (roughly 342 US gallons); space needed is rated “very large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–79 °F, pH 6–7.5, 10–20 dGH.
- Behaviour: temperament peaceful.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Not a good choice for the planted setup, as it will munch most greenery.”
- Diet: “Omnivorous and will accept most foods offered.”
- Breeding: “Not known to have been bred in captivity.”

Distichodus and African characins
Applies to most species in this group. Habitat: These African freshwater fishes inhabit rivers, lakes and ponds, ranging from large Distichodus to small stream-dwelling Nannaethiops (sixband, oneline). Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- D. sexfasciatus: at least 240 × 90 × 60 cm, approximately 1,296 L for one; groups need substantially more space (sixband).
- Nannaethiops unitaeniatus: 60 × 30 × 30 cm, approximately 54 L for a small shoal (oneline).
- Large Distichodus: smooth rocks, wood and some water movement; most plants will be eaten (sixband).
- Fit a heavy, tight cover for jumping Distichodus (sixband).
- Nannaethiops: dense planting, floating cover and subdued lighting (oneline).
Climate & lighting
| Water | 71.6–78.8°F |
Diet
- Distichodus: Spirulina flakes, blanched spinach and shelled peas (sixband).
- Distichodus: earthworms, prawn and mussel (sixband).
- Nannaethiops: small live/frozen invertebrates and algae-based food; dried food may initially be refused (oneline).
Social life
- Adult sexfasciatus can become aggressive; Nannaethiops is shy and peaceful and needs a shoal with gentle companions (sixband, oneline).
Health watch
- Ammonia toxicity from inadequate biofiltration (fish_health).
- Parasitic skin and gill infections (fish_health).
- Nutritional deficiencies from unsuitable diets (fish_health).
Understanding the animal
In the wild
In the wild
From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1
| Where it lives | Lives in freshwater, in rivers and streams, lakes, the intertidal zone. Swim in shoals at the lower water layers of rivers and inshore areas of lake. Feeds on worms, crustaceans, insects and plant matter. |
| Water it lives in | Freshwater, 72–79 °F (22–26 °C), pH 6–7.5, hardness 10–20 dH. |
| Climate | Tropical climate. |
What this means for care
- Keep water within its wild range, 72–79 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 88°F (up to 91°F in the hottest sampled areas) |
| Cool-season lows | about 65°F (down to 62°F in the coldest sampled areas) |
| Average temperature | 75–78°F across sampled records |
| Relative humidity | 76–81% on average (driest month about 72%) |
| Rainfall | about 1607 mm a year |
Measured at 54 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

| Where it lives | Home ranges Population dynamics Growth parameters Max. ages / sizes Length-weight rel. Length-frequencies Mass conversion Recruitment Abundance Life cycle Reproduction Maturity Maturity/Gills rel. — FishBase |
| Appearance and size | Distichodus sexfasciatus can reach a length of 76 cm. The body is high-backed, reddish brown to reddish-yellow colored, with an elongated, partially squat and a laterally flattened head. They are characterized by six dark vertical bands, which are slightly narrower than the spaces between them. — Wikipedia (community-edited) |
| Biology | Swim in shoals at the lower water layers of rivers and inshore areas of lake. Feeds on worms, crustaceans, insects and plant matter. — FishBase |
| Conservation | Per the IUCN Red List of Threatened Species, Distichodus sexfasciatus is considered of least concern. Their main potential threat is the decline in wetland areas due to human influence, but it is noted that the current population trend is unknown and the last assessment was done in 2009. Further work is needed on their current population. — Wikipedia (community-edited) |
