Relevant Information:

Description: These are sometimes sold or seen as I. metae but that species has a more rounded caudal fin (albeit that us not always a reliable indicator as the fin can often be damaged) and also has one more pectoral fin ray (I + 6). I. guayaberensis (Dahl, 1960) also has a similar pattern but that species has even more pectoral fin rays (I + 8). Both I. metae and I. guayaberensis come from further north, in the Orinoco system in Colombia. (Grant, S). Habitat: Lives mainly in little forest creeks with notable current and a sandy-rocky substrate. Aquarium Care: Even although this species is termed, along with other members of this family, as parasitic catfishes it is well behaved in the aquarium but is seldom seen until feeding time. Provide caves/pipes for this species. Diet: It is not known whether it feeds on flesh or blood of living animals or it lives on carrion. Opercle hooks enable it to cling to and to dig little tunnels into its prey's flesh. Etymology: The specific name amazonicus: From the Amazon river basin.

IUCN Red List

This species is widely distributed in the Amazon and Orinoco basins, with many occurrences, especially in Brazil. Research regarding its population trends is needed to better understand the possible pressures of land use change on the species. There is no information about any major threats in the countries where it occurs otherwise. Therefore, it is assessed as Least Concern, (IUCN 2023).
