[5] Said study also contained a redescription of Bryconops caudomaculatus, due to the species' generally enigmatic nature.

It is considered a part of the Bryconops caudomaculatus species complex because of morphological similarities and a history of synonymy therein.

However, research in 2011 by Oliveira et al. moved the genera Bryconops, Piabucus, and Iguanodectes into the family Iguanodectidae, which is where B. magoi currently stands.

All paratypes were collected from the type locality: the Rio Moquete at Paso Bajito, which is located in the Francisco de Miranda Municipality, in the Venezuelan state of Anzoátegui.

It demonstrates a preference for fast-moving water over sandy substrate, and is most often found swimming close to the surface, schooling with other species of fish.

Cursory examination shows that B. magoi feeds at the surface of the water, largely targeting insects that fall in from trees hanging above.

[1] This is a similarity it shares with congener B. inpai, which also has a taste for terrestrial insects and other invertebrates that originate outside of the river system.
