Care at a glance
Species-specific aquarium care
- Tank: At least 72 in long and 27 in front to back for one adult (adults commonly reach about 13.8 in / 35 cm).
- Water: Freshwater (tolerates brackish).
- Temperature: 63–95°F (range recorded for this species).
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
- Diet: A substrate browser: offer sinking foods and let it sift the bottom; use soft sand if it digs. FishBase classes it as a herbivore.
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 83 × 24 in (roughly 200 US gallons); space needed is rated “very large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 70–81 °F, pH 6.2–8.5, 10–30 dGH.
- Behaviour: temperament predatory.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Diet: “Very unfussy and will eat most foods offered.”
- Tankmates: “A very robust species that is territorial when spawning but is otherwise quite peaceful.”

West, Central and southern African river cichlids and tilapias
Applies to most species in this group. Habitat: African rivers, streams and lakes. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Kribensis and other dwarf West Africans do well in planted 20–30 gallon tanks with caves and neutral water.
- Tilapias and Serranochromis grow large and are often kept in ponds or for aquaculture.
Climate & lighting
| Water | 75–82°F |
Diet
- Omnivorous pellets plus frozen foods; tilapias need plant matter.
Health watch
- Several tilapias are invasive and regulated by many states; never release.

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 and brackish water, in rivers and streams, lakes, rice paddies, estuaries. Uses both the bottom and open water. Adults thrive in standing waters. |
| Water it lives in | Freshwater / brackish water, depth 1–12 m. |
| Climate | Tropical climate. |
| Wild diet | Browsing on substrate. |
| Behavior to plan for | Breeding: external brooders. |
What this means for care
- It tolerates or needs brackish water; check salinity needs before setup.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 89°F (up to 98°F in the hottest sampled areas) |
| Cool-season lows | about 51°F (down to 39°F in the coldest sampled areas) |
| Average temperature | 64–80°F across sampled records |
| Relative humidity | 59–76% on average (driest month about 60%) |
| Rainfall | about 935 mm a year |
Measured at 1198 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.

| Overview | The Mozambique tilapia (Oreochromis mossambicus) is an oreochromine cichlid fish native to southeastern Africa. Dull colored, the Mozambique tilapia often lives up to a decade in its native habitats. It is a popular fish for aquaculture. Due to human introductions, it is now found in many tropical and subtropical habitats around the globe, where it can become an invasive species because of its robust nature. — Wikipedia (community-edited) |
| 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 |
| Social life and communication | Mozambique tilapias often travel in groups where a strict dominance hierarchy is maintained. Positions within the hierarchy correlate with territoriality, courtship rate, nest size, aggression, and hormone production. In terms of social structure, Mozambique tilapias engage in a system known as lek-breeding, where males establish territories with dominance hierarchies while females travel between them. — Wikipedia (community-edited) |
| Wild diet | Mozambique tilapia are omnivorous. They can consume detritus, diatoms, phytoplankton, invertebrates, small fry and vegetation ranging from macroalgae to rooted plants. This broad diet helps the species thrive in diverse locations. — Wikipedia (community-edited) |
| Reproduction | Spawns at the edge of the littoral terrace of lakes (, 2, 87, 6465 ), in sandy or muddy bottoms. — FishBase |
| Appearance and size | Maximum length 39.0 cm sl male/unsexed; maximum published weight 1.1 kg; maximum reported age 11 years. — FishBase |
| Biology | Adults thrive in standing waters (, 12501 ). Inhabits reservoirs, rivers, creeks, drains, swamps and tidal creeks; commonly over mud bottoms, often in well-vegetated areas. Also found in warm weedy pools of sluggish streams, canals, and ponds. — FishBase |
