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 with the exception of A. pauciradiatus which will prove to be a Corydoras and if a revision is carried out will be Gastrodermus (Cope, 1878) and a member of Lineage 5 alongside members of the "elegans group". 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.
