Relevant Information:

Was known until recently (2011) as Doras eigenmanni until a new paper by Birindelli, JLO and MH Sabaj Pérez (2011) asigned a new genera, Ossancora to this species. Ossancora was proposed to include three previously named species O. punctata, O. fimbriata plus one new species in O. asterophysa. Description: The four species are distinguished from each other by the branching on the maxillary and mandibular barbels, the morphologies of the swimbladder and bony plates in front of the dorsal fin, and the number of teeth on the upper and lower jaws. Can sometimes be seen, and sold as Opsodoras stuebelii, which has a longer snout and lacks the body and caudal spots and also grows larger. It has been misidentified, especially in the mid 1980s in the hobby when catfish were just beginning to get a fan base in the U. K. Similar to Ossancora punctata (previously Doras punctatus) which has bands in the caudal fin against spots in O.eigenmanni. Aquarium Care: Very peaceful addition to a community aquarium. This is another doradid that prefers safety in numbers assuming that you can purchase them. Recommended that you keep at least 4 specimens together. Good water quality is required. Diet: Finely shredded shrimp and bloodworm. Etymology: The specific name eigenmanni: In honour of German-born American ichthyologist Carl H. Eigenmann (1863–1927), author of an “excellent” synopsis (1890) of South American catfishes.
