Adrianus Franciscus Johannes Marinus Maria "Ad" Konings[1] (born 11 January 1956 in Roosendaal, Netherlands) is an ichthyologist originally trained in medicine and biology.
Soon he was breeding rare African cichlids and working as an assistant to the largest tropical fish dealer in the Netherlands.
In 1986, Konings moved to St. Leon-Rot, Germany (near Heidelberg), where he started to write books and breed Lake Tanganyika cichlids.
Late in her career famed ichthyologist Ethelwynn Trewavas mentored Konings, providing feedback and suggestions for his research.
Konings also was mentored by prominent fish explorer and exporter Stuart Grant early in his career, and when Konings married his wife Gertrud (nḗe Dudin), also a biologist, in 1996 in Malawi Grant and his wife Esther were best man and maid of honor.
