Stomach content analysis based on three specimens reveals that this species feeds mostly on vegetal matter (macrophyte fragments, unicellular and filamentous algae), and a smaller proportion of other organisms (testate amoebae, Cladocera, aquatic Hemiptera, Chironomidae larvae, unidentified invertebrate eggs). Observed during snorkeling sessions to browse on the periphyton growing on the surface of large submerged macrophytes leaves (Nymphaeaceae). Occurs syntopically at Lagoa Azul with other characids including Thayeria sp., Hemigrammus sp., Moenkhausia ceros, M. cotinho, M. colletti, and M. cf. lepidura, as well as several cichlids, anostomids, poeciliids, and stingrays (Ref. 94770).

It differs from H. bifasciatus, H. cyanotaenia, H. heliacus, H. igneus, H. loweae, and H. peugeoti by having octa- to decacuspid inner premaxillary teeth (vs. tetra- to pentacuspid in H. bifasciatus and H. igneus, heptacuspid in H. heliacus, penta- to heptacuspid in H. cyanotaenia and H. loweae, and hexa- to heptacuspid in H. peugeoti), and by having dark chromatophores concentrated on the posterior border of the body scales, forming a reticulated color pattern (vs. reticulated pattern absent). It can be separated from Hyphessobrycon heliacus, H. loweae, and H. peugeoti by the absence of an elongated, filamentous dorsal fin in adult males (vs. elongated, filamentous dorsal fin present in adult males). It further differs from H. bifasciatus by having a single humeral blotch (vs. two well-defined humeral blotches) and from H. bifasciatus and H. igneus by having 17-20 branched anal-fin rays (vs. 27-32 in H. bifasciatus, and 23-29 in H. igneus) and by the absence of hooks on anal fin in mature males (vs. presence in H.bifasciatus and H. igneus) (Ref. 94770).
