Relevant Information:

M. potaroensis is a demersal (living at or near the bottom of the water body) species. The species is very habitat specific, living on banks of submerged litter, in rivers with relatively fast flow. Can occur in relatively small forest streams with sufficient flow to keep the litter banks from becoming anoxic. Remarks: Brachyglanis, Leptorhamdia and Myoglanis along with Gladioglanis and the members of the Nemuroglanis subclade (Ferraris 1988) were assigned by Lundberg et al. (1991) to a large unnamed monophyletic group characterized by the loss of a free orbital rim around the eye. For further information read the referenced paper by DoNascimiento, C. and J.G. Lundberg, 2005.
