Etymology
The fish is named in honor of Dutch ichthyologist Alex Ploeg, whose Ph.D. thesis dealt with the taxonomic revision, biogeography and phylogeny of Crenicichla, and who published papers on the systematics of the genus from 1986 to 1991, describing a total of 23 species, eighteen of which are still considered valid; afterwards, he worked as interlocutor between the ornamental fish industry and other institutions worldwide, before losing his life, along with his wife and son and son’s friend, when Malaysia Airlines flight MH17 was shot down by a missile over the Ukraine on 17 July 2014.
