Relevant Information:

Can be easily mixed up with Synodontis nigrita, but the main difference is the body colour with S. nigrita having a grey/black colouration and robbiana being more of a brown colour. There is also a difference in the shape of the humeral process ( the part of the head shield that projects back just above the pectoral fins), S. robbiannus is that bit longer and ends in a point while nigrita also ends in a point but is shorter and sweeps up in a curve on the bottom edge. Aquarium Care: One of the more peaceful Synodontis species. Good community catfish in a larger setup but as with all Syno's will need their own space, meaning their own bit of bogwood, PVC pipe or rockwork to reduce the territorial behaviour of this genus. Diet: Will take most prepared aquarium foods such as frozen bloodworm, whiteworm, shrimp, prawns, tablet food, flake food and pellets. A wide varied diet will provide a healthy specimen for many years.
