The natural range of this species is eastwards from eastern Pakistan up to Borneo and Java (Wowor and Ng 2007, as M.dacqueti). The species is widely cultured both within its natural range and far beyond (Africa, South America). Established populations of aquaculture escapees have been recorded in Para, Brazil (Silva-Oliviera et al. 2011) and Martinique (Lim et al. 2002). Further specimens have been in Sao Paulo state, but these may represent a non-breeding population.
