Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 2.6 in / 6.7 cm).
- Water: Freshwater.
- Temperature: 73–81°F (range recorded for this species).
- pH: 7.4–8.4.
- Hardness: 7–30 dGH.
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.
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
- Water: hard, alkaline water, 73–81 °F, pH 7.5–9, 8–25 dGH.
- Behaviour: temperament peaceful.
- Difficulty: Easy (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Should be housed in a Lake Tanganyika biotope setup, with piles of rocks arranged to form caves filling much of the aquarium.”
- Diet: “Live and frozen foods should comprise a large proportion of the diet.”
- Tankmates: “A relatively peaceful species, although very territorial when breeding and is best kept in a species tank.”

Lake Tanganyika cichlids
Applies to most species in this group. Habitat: Rocky reefs, shell beds and sand of Lake Tanganyika. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Use species-specific alkaline-water parameters and stable, well-oxygenated conditions. For N. multifasciatus, Seriously Fish gives pH 7.5–9.0 and general hardness 8–25 dGH.
- Shell-dwellers need beds of empty snail shells; rock-dwellers like Julidochromis need stacked rockwork; Tropheus need large groups and spacious tanks.
Climate & lighting
| Water | 76–81°F |
Diet
- Tropheus moorii needs a vegetable-based staple with small suitable live/frozen supplements. Other Tanganyikans need their own feeding plan; shell-dweller and predator diets differ.
Social life
- Often pair- or colony-forming and territorial; research each genus.
Health watch
- Tropheus are prone to bloat on rich foods; sudden water changes stress Tanganyikans.
