A presenting a dominance of d = 0.28; during the period of receding water, a predominance of Characidae (92 fish sampled) was observed, with Hemigrammus ureyi presenting d = 0.19; in low water, Loricariidae were more abundant, with 184 individuals, all of the species Hypoptopoma inexspectatum (d = 0.82).
Axis 1 was characterized by the species variation, Hyphessobrycon diastatos, Hisonotus vespuccii, and Hemigrammus gracilis, which were related to higher altitudes, greater water superficial velocity and large substrates.

A phylogenetic reconstruction is needed that includes the type species to begin to unravel the phylogenetic relationships of the species of Hyphessobrycon sensu lato, the group to which Hyphessobrycon natagaima belongs, and to determine the limits of Hemigrammus. Until such a hypothesis is available, relationships will continue to be based on apomorphic and ambiguous characters.

(1998) reported a similar feeding habit for Cichla orinocensis Humboldt, 1821 in Guri Reservoir, which foraged mostly in shallow, structured habitats within littoral zone where Crenicichla wallacii Regan, 1905, other cichlids, and the characid Hemigrammus micropterus Meek, 1907 were the dominant preys.

The seven species of small-sized fish species that coexisted in the nine ponds included in this study were: Astyanax altiparanae (Garutti; Britski, 2000) (28-106 mm SL); Astyanax jasciatus (Cuvier, 1819) (38-76 mm SL); Bryconamericus stramineus Eigenmann 1908 (18-45 mm SL); Hemigrammus marginatus Ellis, 1911 (23-49 mm SL); Hyphessobrycon eques (Steindachner, 1882) (12-34 mm SL); Moenkhausia intermedia Eigenmann, 1908 (19-68 mm SL) and Moenkhausia sanctaefilomenae (Steindachner, 1907) (14-46 mm SL).
These macrohabitats shared 37 species comprising the largest assemblage of ornamental and relatively smaller species (<120mm standard length), such as those in the Astyanax, Ancistrus, Apareiodon, Apistogramma, Bujurquina, Characidium, Cheirodon, Corydoras, Hemigrammus, Holoshesthes, Moenkhausia, Otocinclus, Odontostilbe and Xenurobrycon genera.
