Can be easily mixed up with Synodontis
the main difference is the body colour with S.
nigrita having a grey/black colouration and robbianus
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 S. 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.
Lower Niger and Cross River (Old Calabar) in Nigeria.
