Kinkony (Lake)

Pachypanchax arnoulti is a killifish endemic to western Madagascar, where it occurs in the Mahavavy du Sud and Betsiboka river systems. It was in the hobby for many years as the congener P. omalonotus and appears under that name in most older aquarium literature, so a degree of hybridisation has undoubtedly occurred. The absence of metallic gold spots on the flanks separates it from that species. Its populations have declined dramatically since the 1950s.
