Aphyosemion gabunense was discovered in 1974 and by 1974 was being bred in Europe. In 976 what was thought by some (Radda) to be new species wer found and described by Radda. Wildekamp in his boo declared they aere all subspecies and it took years to prove they were different species. Regardless, they are easy to keep fish that are not wuite as shy as others. Not difficult to bred, although being from Gabon they almost certainly need soft water to breed. Eggs take 10-14 days to hatch.
A. boehmi was discovered in Gabon in 1976 by Bochtler and Gasper on the G76 collecting trip. Presumably both A. boehmi and A. marginatum were collected as there are no records or any other trips to Gabon finding (what was then thought to be) subspecies of A. gabunense. Both BOE and MRG were described by Radda and Huber in 1977. BOE is found only in the Ngounie River Western Gabon.
All three were once thought to be subspecues of A. gabunense: A. gabunense gabunense, A. gabunense boehmi and A. gabunense marguinatum. Radda and Huber argued they were valid spcies or subspecies, Wildekamp claimed thy were all A. gabunense. In a 2022 work, Van der Zee, based on molecular data, eleveted them all to full species status.
