In the small stream they were found in small shoals of about 3-5 individuals swimming near the surface, while in the Lago Tiburiari this species formed larger shoals of about 20 individuals. Found sympatrically was the miniature scoloplacid, Scoloplax dolicholophia (Ref. 123788), Bragança, P.H.N. 2018 Fluviphylax gouldingi and F. wallacei, two new miniature killifishes from the middle and upper Rio Negro drainage, Brazilian Amazon (Teleostei, Cyprinodontiformes, Cyprinodontoidei).

Other characters not unique but useful to identify tis species include: second and fourth pharyngobranchial tooth plates not enlarged (vs. enlarged); no teeth on second pharyngobranchial plate (vs. present); ventral process of posttemporal short (vs. long); with rostral cartilage (vs. absent); anterodorsal process of opercle non-existent (vs. present); an elongate and pointed anal fin reaching vertical to dorsal-fin tip (vs. short and rounded) (Ref. 123788).
