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 (1303 clear days). The rainy-season months are usually too cloudy to measure and are left blank.

The site
Captions place the type locality of Chalinochromis cyanophleps just west of Namansi Village, describing rocks at the site.
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.
