Tramitichromis intermedius is a species of cichlid endemic to Lake Malawi where it is found in the southern parts of the lake preferring the shallows of sheltered bays.
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 6.3 in / 16 cm).
- Water: Freshwater.
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- 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 × 15 in (roughly 46 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 peaceful.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “A soft sandy substrate is essential so that the fish can feed naturally, and as much floorspace as possible should be provided with the aquarium being no less than 15" in width.”
- Diet: “A micropredator in nature; it thrives on a varied diet containing lots of frozen and live foods.”
- Tankmates: “A peaceful species which is not suited to the boisterous mbuna community although it does become territorial when 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.

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 lakes. Stays near the bottom. Found in very shallow waters of sheltered bays. Feed on insect larvae and other soft invertebrates. |
| Water it lives in | Freshwater. |
| Climate | Tropical climate. |
| Wild diet | Hunting macrofauna (predator). |
| Behavior to plan for | Breeding: external brooders, maternal parental care. |
What this means for care
- Parents guard eggs or young, so expect territorial behavior when breeding.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 88°F (up to 89°F in the hottest sampled areas) |
| Cool-season lows | about 60°F (down to 51°F in the coldest sampled areas) |
| Average temperature | 68–76°F across sampled records |
| Relative humidity | 67–68% on average (driest month about 55%) |
| Rainfall | about 1035 mm a year, with strong wet and dry seasons |
Measured at 5 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.
