Abstract
The sailfin molly, Poecilia latipinna (Lesueur, 1821), is a popular aquariwn fish, native to the eastern coastline of North America. It has been introduced to many countries worldwide as biological control agent and through releases from aquarium hobbyists. The aim of this paper is to report the presence of sailfin molly in a brackish lake in northern Egypt (Lake Manzala). Twenty-five individuals (8 males and 17 females) of sailfin molly were incidentally collected while fishing for tilapia fish in the lake. All individuals were identified as P. latipinna based on morphological features and this is possibly the first documented record of sailfin molly in Africa.
