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) (~27 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 82 °F — coolest in Jul. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (1725 clear days). The rainy-season months are usually too cloudy to measure and are left blank.

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.
