The loop for suspension at the mouth of the fish shows that it would have hung vertically as a pendant. Its overall shape with a sharp dorsal fin allows to determine that this is a Synodontis batensoda. More detailed pendants confirm this identification. This type of catfish often swims upside down very close to the surface and is hence also called the "upside-down catfish."
