Synodontis angelicus is a species of upside-down catfish commonly named polkadot squeaker, black clown catfish, whitespotted squeaker, pearl squeaker, or angel squeaker. This species is native to the Congo Basin of Cameroon, the Democratic Republic of the Congo and the Republic of the Congo. It was originally described in 1891 by Belgian icthyologist Louise Schilthuis after its discovery in the Malebo Pool of the Congo River. The specific name "angelicus" means heavenly or devine, since juveniles of this species are remarkable for their bright coloring.
