Assessor(s): Reis, R & Lima, F.
Reviewer(s): Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)
Assessed as Least Concern due to the species inhabiting a remote area, within mature, undisturbed forest in a national park. In addition, there are no known major threats to this species. However, as it has only recently been described and is only known from one specimen, further research into population numbers and the range of G. niobium would be beneficial, to confirm this species' status.

Habitat and Ecology [top]

Habitat and Ecology:It is a benthopelagic (ecological region at the lowest level of water body) species, and is the only known fish so far known to occur in the remote Morro dos Seis Lagos lake complex, which is a region with high levels of natural radioactivity (de Pinna 1998).

G. niobium is currently only known from one specimen, which was collected in water about 1m deep, hiding within a thick layer of leaf litter on the bottom.
