Hongi Island is an island off Lake Malawi's Tanzanian shore, under 1 km south-west of Hongi Rocks.
Where it is
Hongi Island is on the eastern shore of Lake Malawi, in its central third (116 mi south of the lake's northern tip).
Nearest collection points: Hongi Rocks 0.1 mi north-east · Lipingo Rock 3.1 mi south-east · Liuli 3.3 mi north
Shore, third and distances are measured from the coordinates above against the lake’s mapped outline.
The water
Lake-wide measured chemistry of Lake Malawi — collection points share their lake's water; site-specific figures are shown only where the literature records them.
Nearest measured station: Salima (south-east shore) (~291 km) — Conductivity 235 µS/cm
Surface temperature here
Across May–Nov, monthly means run 76 °F to 82 °F — coolest in Aug. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (890 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.
