Care at a glance
Species-specific aquarium care
- Tank: At least 30 in long and 12 in front to back for one adult (adults commonly reach about 5.6 in / 14.1 cm).
- Water: Freshwater.
- 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 47 × 18 in (roughly 54 US gallons); space needed is rated “large tank”.
- Water: hard, alkaline water, 75–82 °F, pH 7.6–8.8, 10–25 dGH.
- Behaviour: temperament territorial.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Much of the aquarium should contain piles of rocks arranged to form caves with small areas of open water between.”
- Diet: “It will accept most foods offered but live and frozen varieties should form the bulk of the diet.”
- Tankmates: “A gentle species which is not suited to the boisterous mbuna community although it does become territorial when breeding.”
- Breeding: “No information available regarding captive breeding.”

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.
