Fin's Fish Guide
The Royaux's suckermouth catfish (Euchilichthys royauxi) is a freshwater fish of the family Mochokidae that grows up to 22 cm.
Description
Royaux's suckermouth catfish is an African catfish of the squeaker family (Mochokidae) from the Congo basin. The species grows to about 22 cm and has a flattened body with a downward-facing, sucker-like mouth with fringed lips, with which it clings to stones in flowing water and scrapes off growth. It inhabits fast-flowing river sections. As a bottom scraper it feeds on algae, periphyton and small invertebrates. Like other Mochokidae it has stout pectoral and dorsal spines that can cause painful injuries. The species is oviparous; handle it carefully because of the spines.
