وصف مختصر
الوصف الخارجي | قياسات المظهر الخارجي
الأشعة الظهرية الناعمة (المجموع): 10-11; أشعه شرجية لينه: 21 - 25; فقرات: 31 - 34. Hyphessobrycon montagi is distinguished from all its congeners, with exception of H. balbus, H. bifasciatus, H. columbianus, H. condotensis, H. flammeus, H. griemi, H. isiri, H. itaparicensis, H. savagei, H. sebastiani, H. togoi, H. tortuguerae, and H. weitzmanorum, by having two well-defined humeral blotches. It differs from all these species by the having the following characters: a well-defined caudal peduncle blotch (vs. caudal peduncle blotch absent in all aforementioned species, with the exception of H. isiri and H. togoi); a horizontally-elongated oval, very well-defined first humeral blotch (vs. first humeral blotch moderately conspicuous, vertically elongated, and approximately rectangular in shape); and first and second humeral blotches are connected via a narrow, short stripe (vs. humeral blotches not connected) (Ref. 97524).
Found only in clear-water terra firme streams, i.e., streams dissecting the uplands, above the periodically flooded igapó forest, as the Igarapé Socó Barroso, the type locality. These streams have width ranging from 0.80 to 20 m, moderate water current (0.1-0.7 m/s), clear,
sandy bottom with pebbles, mud, leaf litter, and submerged logs, often also presenting aquatic macrophytes, pH ranging from 5.8 to 7.44, and water temperature ranging from 24.9° to 29.1°C. Ripe oocytes were observed in females collected in March and August (Ref. 97524).
