Description

Synodontis alberti, the bigeye squeaker, is an African catfish of the family Mochokidae from the Congo basin in Central Africa. The species has an elongate, spotted body with conspicuously large eyes and very long, branched barbels, and reaches about 20 cm. It is nocturnal and lives on the bottom of rivers, where it probes for food with its long barbels and feeds on small invertebrates, insect larvae and plant matter. Like other squeakers it can make squeaking sounds with its pectoral fins and bears strong fin spines. Owing to its elegant appearance the species is popular in the aquarium trade.
