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 4.5 in / 11.41 cm).
- Water: Freshwater.
- 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
- Tank: a base of at least 59 × 18 in (roughly 80 US gallons); space needed is rated “very large tank”.
- Water: hard, alkaline water, 77–84 °F, pH 7.5–8.5, 10–25 dGH.
- Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “As it's an open water species it needs plenty of swimming space.”
- Diet: “Copadichromis are specialised zooplankton feeders, although they usually prove to be unfussy in captivity.”
- Tankmates: “A generally peaceful species.”
- Breeding: “Has been bred regularly in the hobby.”

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.

| 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 |
| Reproduction | The spawning site usually is constructed under and against a rock or small group of rocks; the male excavates the sand from beneath the rock and heaps it up, building a semicircular wall around the spawning site, sometimes leaving just a narrow opening to the nest. The spawning sites are usually about 2 meters apart. — FishBase |
| Biology | Males build their spawning sites at depths of approximately 25 meters or deeper; females, in particular mouth brooding females, can be found in shallower water, but they rarely venture into regions shallower than 10 meters. — FishBase |
