In this study, the epiphytic algae of Lemna minor collected from its natural habitat or grown in aquarium were analyzed for a period of six months from April 2016 to September 2016. While a total of 15 taxa, 1 belonging to Cyanophyta and 14 belonging to Bacillariophyta, were recorded for L. minor grown in aquarium, a total of 36 taxa, 3 belonging to Cyanophyta, 5 belonging to Chlorophyta, 1 belonging to Euglenophyta, and 27 belonging to Bacillariophyta, were recorded for L. minor collected from its natural habitat. While no monthly differences were detected among those species emerging in aquarium, differences were observed among species emerging in the natural habitat.
