Surface temperature here

Across Apr–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 (907 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.
