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 2.8 in / 7.1 cm).
- Water: Freshwater.
- Temperature: 72–79°F (range recorded for this species).
- pH: 7.4–8.
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- Diet: A predator: feed meaty foods sized to its mouth (frozen fish, shrimp, worms); it will eat tankmates that fit in its mouth. FishBase classes it as a carnivore.
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 35 × 18 in (roughly 48 US gallons); space needed is rated “large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–79 °F, pH 7.4–9, 10–25 dGH.
- Behaviour: a shoaling fish best kept in a group of six or more; suited to a community tank.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Arrange some piles of rockwork around the tank but leave some open spaces between them and use fine sand as substrate so that it's able to feed naturally (see 'diet').”
- Tankmates: “A relatively peaceful species although males tend to act aggressively towards any fish with a similar colour pattern, so take care when selecting tankmates.”
- Breeding: “Maternal mouthbrooder which will often spawn in a community set-up, but should be moved or maintained in a specific tank if the intention is to maximise yield.”

Lake Malawi peacocks and haps
Applies to most species in this group. Habitat: Open water and sand of Lake Malawi. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Hard, alkaline water (pH 7.8–8.6), a long tank (5 ft+ for larger haps) with open sand and some rock.
- Generally less aggressive than mbuna; males color up best with several females.
Climate & lighting
| Water | 76–82°F |
Diet
- For Aulonocara stuartgranti, use small prepared foods with some vegetable content and varied small live/frozen invertebrates. Match other haps to their own feeding ecology.
Health watch
- Do not diagnose bloat from a label such as “mbuna-style food”; Aulonocara stuartgranti diets can include vegetable foods. Match food and tankmates to the species.
Understanding the animal
About this animal
About this animal
It occurs over habitats of mixed rock and sand and it feeds on benthic invertebrates. The males show territorial behaviour all year and defend their territories from other males.

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 lakes. Uses both the bottom and open water. Found over sand in intermediate habitats where rocks are lying over sand. Feeds on bottom-dwelling invertebrates. |
| Water it lives in | Freshwater, 72–79 °F (22–26 °C), pH 7.4–8. |
| Climate | Tropical climate. |
| Wild diet | Hunting macrofauna (predator). |
What this means for care
- Keep water within its wild range, 72–79 °F.

| Overview | The Chitande aulonocara (Aulonocara ethelwynnae) is a species of haplochromine cichlid which is endemic to Lake Malawi, only occurring in the north-west of the Lake near Chitande Island. It occurs over habitats of mixed rock and sand and it feeds on benthic invertebrates. The males show territorial behaviour all year and defend their territories from other males. These territorial males are found in deeper areas around 15 m while the non territorial males and the females are rarely seen below 3 m. — Wikipedia (community-edited) |
