This species was for many years thought to be Aspidoras eurycephalus but with further investigation by Ichthyologist Luiz Tencatt found out that it is an undescribed species and what we thought as A. eurycephalus is a different species altogether. 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. Many species of Aspidoras are difficult to tell apart unless there is area catchment information available. 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 sp. (CW119) has been placed in Lineage 2 and has retained the genus name of Aspidoras . Aquarium Care: Inoffensive catfish which will suffer at the hands of aggressive tank mates. Will do well in a species tank or a community tank with smaller inmates such as tetras and rasboras. Best to keep in a shoal of at least four. Diet: Prefer live foods such as newly hatched brine shrimp but will also take frozen food and a good quality flake, plus tablet food. Remarks: CW119 and C125 have both been proved to be Aspidoras raimundi. Many species of Aspidoras are difficult to tell apart unless there is area catchment information available.
