📖 Overview

This species was collected only from mountain springs that lead to the lake, apparently an endorheic drainage. Site collection is a clear water path with slow current exiting the lake (water temperature 29.9 °C and conductivity 321 microS/cm on the June 5, 2019). 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.) .
