| History |
Boulenger based his description of Haplochilus
striatus on 4 specimens collected by Ansorge between the first &
second rapid on the Abanga River. This was a northern affluent of the Ogowe drainage,
Gabon. Boulenger gives the following collectors / locations in his 1915 Catalogue.
A group of BKA members made a tour of European killie keepers in 1973. A.striatum were obtained & fish were distributed to Species Control members. Probable first release into the BKA was at the Collingham AGM in October 1973. | ||||||||||||
