Schall Squeaker

Synodontis schall is among the largest members of its genus, reaching 42 cm and developing a robust, deep-bodied form quite different from the streamlined profile of smaller squeaker catfish. It is widespread across the Nile basin and West African river systems, inhabiting large rivers, floodplains, and lake margins. Its bold dark-spotted pattern on a grey-brown background is attractive and remains vivid throughout life.

In the aquarium, S. schall is more vigorous and assertive than smaller Synodontis species. It is semi-aggressive and may bother passive tankmates, particularly at feeding time when its competitive nature is most apparent. Despite this, it rarely causes serious injury and can be housed with other robust large African fish. It is primarily nocturnal but becomes increasingly bold once settled.

Feeding is uncomplicated — like all Synodontis it is an enthusiastic omnivore accepting practically any food that reaches the bottom. Sinking wafers, frozen bloodworm, prawns, and vegetable matter are all taken readily. Its longevity (10–15 years) and striking size make it a long-term commitment well worth making.

Water: 22–27°C, pH 7.0–8.0, moderate to hard; tolerates Lake Victoria/Nile conditions. Tank: 400 L minimum; large smooth caves; driftwood; fine to medium substrate. Feeding: Sinking wafers, frozen bloodworm and daphnia, prawns, vegetable matter; hearty feeder. Breeding: Cave spawner; occasional reports in large tanks; male guards eggs and fry. Compatibility: Semi-aggressive; avoid very small or timid tankmates; best with large cichlids and other robust species.
