Paracanthopoma ahriman is a species of vampire catfish from the family Trichomycteridae. It was described in a 2022 taxonomic review of the vampire catfish genus Paracanthopoma by "de Pinna, M. C. C., & Dagosta, F. C. P." Habitat: It occurs in the upper Orinoco River basin, Venezuela. Species of Paracanthopoma are broadly distributed in the northern cis-Andean South American drainages, namely Amazon, Orinoco, and Essequibo, with a single locality also in the Upper Paraguay. Aquarium Care: Not easy to keep and would need to be housed on their own as larger fish would be preyed upon for their blood in the gill chambers. Sand is the best substrate for digging themselves into and floating plants to cut the light down for this light sensitive species. Diet: Very difficult as all reports seem to intimate that they need larger fish to feed on. Etymology: The genus name Paracanthopoma: pará (Gr.), near, referring to similarity to Acanthopoma (Stegophilinae), both of which possess united gill membranes that are free from the isthmus. The specific name cangussu: Named for the Canguçu Research Centre, managed by the Federal University of Tocantins (Brazil), for their support of the authors’ study.
