Along with other descriptions made by Fowler in 1913, eight specimens of T. madeirae, including the holotype and the paratype, were collected by Edgar A. Smith during a 1912-1913 expedition to the Amazon basin in Brazil along the Madeira River.[4]
In his description, Fowler named the species for the Madeira River.[4]
Tyttocharax madeirae has been found in the lower and middle tributaries of the Amazon basin,[3] being found in the nations of Brazil, Bolivia, and Peru.[4][6][7] It is pelagic,[3] and according to observations by Herbert R. Axelrod were found in shallow waters 0.3 to 0.6 meters deep (1 to 2 feet) at most.[2]
In a sampling expedition by Barros et al., T. madeirae accounted for 0.82% of the total 5508 collected specimens and occurred in 13.6% of the sampled streams of the Madeira-Purus interfluvial plain.[8]
Fowler did not describe the colors of a living T. madeirae, however, it was described as palish brown when in alcohol, exhibiting countershading with a paler underside.[4]T. madeirae is considered small, with the average length of the species being 1.5 cm (0.59 inches) and ranging from 1.1 to 1.8 cm (0.43 to 0.71 inches).[4][9]
Tyttocharax madeirae is an invertivore, specializing on aquatic invertebrates while also occasionally preying on terrestrial vertebrates which may fall into the water.[9]
