The Aspidoras genera differ from Corydoras by their different behaviour such as their swimming habits. 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 raimundi has been placed in Lineage 2 and has retained the genus name of Aspidoras. Aquarium Care: Aspidoras raimundi 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 raimundi: patronym not identified, perhaps, as suggested by Nijssen & Isbrücker (1976), a Brazilian associate of Steindachner; another possibility: Raimund Banowsky (d. 1885), a contemporary of Steindachner at the Zoological and Botanical Society of Vienna. Remarks: This species will encompass A. menezesi and A. spilotus as synonyms as they are seemingly all the same species. C125 and C119 are also the same species. Many species of Aspidoras are difficult to tell apart unless there is area catchment information available.
