Exallodontus is classified under the "Calophysus-Pimelodus clade". Within this clade, it is considered a part of the "Pimelodus-group" of Pimelodids, which also includes Pimelodus, Duopalatinus, Cheirocerus, Iheringichthys, Bergiaria, Bagropsi, Parapimelodus, Platysilurus, Platystomatichthys, and Propimelodus. Aquarium Care: Looks a bit like Pinarampus pinirampu, which gets much bigger (up to 1 metre and more). In my opinion Exallodontus aguanai is not really a good predator catfish species for the home aquarium because it is always nervous, and with its hectic movements especially at night, it makes the other fish nervous too. Can be kept alone or with other E. aguanai specimens. Can be kept with other species only if they are not too small and bigger species only if they are not aggressive. Prefers a strong current. he only advantage with keeping, is its final  length (= ca. 20-25 cm) (Wolfgang Ros, pers comm 2008). Diet: Feeding is easy, because it takes all kind of food (small live but also pieces of fish filet, also tablets, pellets, even Tetra Min flakes) (Wolfgang Ros, pers comm 2008). Etymology: The specific name aguanai: In honour of Leonidas Aguana, Universidad Central de Venezuela, whose friendship and “intrepid collaboration in the field” have contributed greatly to the authors’ research and to Venezuelan ichthyology. Remarks: The first six images by the image contributor depicts an adult specimen of 20cm. (8ins) SL.
