Occurs on muddy bottoms and some semi-submerged and submerged vegetation growing near the banks. Sympatric with Gambusia beebei, Limia miragoanensis, L. immaculata, L. nigrofasciata, L. garnieri, L. islai), Nandopsis haitiensis and two species of African cichlids introduced in the lake (Oreochromis aureus and Tilapia sp.)
