Mvuna Island is one of a small group of islands off Tanzania's Lake Tanganyika shore near Kipili, alongside Ulwile, Lupita, and Kerenge Islands.
Where it is
Mvuna Island is in open water about 3.1 mi off the eastern shore, in the southern third of Lake Tanganyika (284 mi south of the lake's northern tip).
Nearest collection points: Lupita Island 1.4 mi south-east · Kasisi Island 2.7 mi north-east · Mlowa Point 3 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) (~159 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 77 °F to 81 °F — coolest in Jul. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (1241 clear days). The rainy-season months are usually too cloudy to measure and are left blank.

The site
Maenga, a dive site noted in early photographs of the group, lies just off the island.
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.
