Long-nosed Squeaker

Synodontis longirostris is immediately identifiable by its markedly elongated snout, far longer than any other Synodontis species, which it uses to probe deep into rock crevices, woody debris, and fine substrate in search of insect larvae, small crustaceans, and organic detritus. It inhabits the Congo River and its major tributaries — one of the world's most biodiverse freshwater systems. Its colouration is variable, typically showing a pale grey-brown base with irregular dark spotting.

In the aquarium, S. longirostris is somewhat more demanding than its hardier relatives, preferring clean, well-oxygenated water and a tank with plenty of crevices and rough surfaces to explore with its distinctive snout. It is semi-aggressive in the usual Synodontis fashion but rarely causes serious harm to tankmates. It is primarily nocturnal and may remain hidden during daylight hours until well-settled.

This species is prized by Synodontis collectors for its unique morphology. It appears sporadically in Congo basin import shipments and commands a premium over common squeaker species. Correct water quality is important — it is less forgiving than most Synodontis.
