Where it is
Mzwema is in open water about 6.8 mi off the eastern shore, in the southern third of Lake Tanganyika (316 mi south of the lake's northern tip).
Nearest collection points: Mtosi 6.2 mi south-east · Lwilwi Island 6.2 mi north-east · Semwe Rocks 6.8 mi east
Shore, third and distances are measured from the coordinates above against the lake’s mapped outline.
The water
Lake-wide measured chemistry of Lake Tanganyika — collection points share their lake's water; site-specific figures are shown only where the literature records them.
Nearest measured station: Mpulungu (south basin) (~106 km) — Temperature 24.5 °C · pH 8.9 · Conductivity 662 µS/cm · Visibility (Secchi) 11.9 m
Surface temperature here
Across Apr–Nov, monthly means run 76 °F to 81 °F — coolest in Jul. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (1466 clear days). The rainy-season months are usually too cloudy to measure and are left blank.
Temperature: ESA Climate Change Initiative, Lakes_cci v3.0 (Asfour et al. 2026; doi:10.5285/a56dba09df8a42ec9fba8b8c7a5e1f69). Chemistry on this page remains the lake's own.
Each entry below is the population of that species recorded here — the form aquarists keep and breed as a distinct, provenance-labelled line. Crossing forms from different collection points is considered hybridisation in the hobby.
