Synodontis nigriventris is the scientific name of the blotched upside-down catfish, a small mochokid catfish from the middle Congo River basin. This species is best known for its habit of swimming and resting upside down, a behavior that allows it to feed efficiently from the undersides of surfaces and gives it one of the most distinctive profiles among aquarium catfishes. In the aquarium, Synodontis nigriventris is generally appreciated as a peaceful, nocturnal species, but it should be provided with shaded hiding places, stable water conditions, and tankmates that will not outcompete or harass it, as understanding its natural behavior is essential for keeping this unique catfish in good condition.
