Relevant Information:

Description: Aspidoras brunneus can be distinguished from all of its congeners by having a wide, longitudinal, conspicuous dark brown stripe along dorsal portion of flank (vs. absence of such stripe). Additionally, it can be distinguished from A. aldebaran, A. belenos, A. depinnai, A. fuscoguttatus, A. maculosus, A. poecilus, A. psammatides, A. raimundi, and A. rochai by having nuchal plate entirely covered by a thick layer of skin (vs. nuchal plate with at least posterior portion exposed). The Aspidoras genera differ from Corydoras by their different behaviour such as their swimming habits (Tencatt et al.). The eyes are smaller, body smaller and a smaller head shape in Aspidoras compared with Corydoras. Aspidoras posses a duel fontanel bone structure in the skull whereas Corydoras have only the one larger fontanel. Lineage: All Aspidoras belong to Lineage 2 and when there is a revision they will stay as Aspidoras von Ihering, 1907 with the type species of A. rochai Ihering, 1907. As of the latest update (Dias et al 2024), Aspidoras brunneus has been placed in Lineage 2 and has retained the genus name of Aspidoras. Aquarium Care: Aspidoras brunneus is fairly uncommon in the hobby but as with all of this genus they are best kept in groups of six or more and are best housed with small fishes that are not aggressive. Provide a planted area in the tank for cover and include a soft substrate such as sand or small rounded gravel. Diet: Flake, tablet foods, small live and frozen foods. Etymology: The specific name brunneus: Medieval Latin for brown, referring to the dark-brown colour pattern. Remarks: Many species of Aspidoras are difficult to tell apart unless there is area catchment information available.
