Fish specimens were preserved and deposited in the Royal Museum for Central Africa (RMCA) following the museum's standard procedures. Subsequently, the specimens were dissected, and the gut contents were examined for diatoms. The South African material consisted of an epilithic sample collected from rocks and cobblestones during routine water quality monitoring in the Nsikazi River. Diatom samples were cleaned using standard methods and examined using light microscopy (LM) and scanning electron microscopy (SEM). Species identification was based on morphological characteristics and relevant taxonomic literature.

Multiple valves or frustules may have been observed within each occurrence.","qualityControl":"Species identifications were verified by diatom specialists using LM and SEM observations.
