Comments: Specimens were collected in the lower portions of igarapé Jamari, in the transition zone between lotic river habitats and lentic habitats of varzea lakes. In igarapé Jamari, the water current was virtually absent. Individuals were observed actively swimming on the surface or in the mid-column in places illuminated by light bulbs close to the shoreline or on boats. All specimens were collected during the night, either by seining (a sandy beach) or with dip nets while swimming in illuminated areas. Fish assemblages at these localities are highly diverse, with species mainly from the white-water floodplains, but including some that are typical of clear water rivers that flow from the Guiana Shield, such as <i>Hoplarchus psittacus</i>, <i>Hypancistrus</i> sp., <i>Otocinclus mura</i> and <i>Peckoltia vittata</i>. Among the other 151 species collected syntopically with this species, <i>Tatia nigra</i> was the only other Centromochlinae. Local fishermen reported that this species is caught and sold for the aquarium trade, although not a primary target (Ref. 118068).
