Description

The Borelli's pencil catfish is a pencil catfish (Trichomycteridae) from fast-flowing, clear fresh water of southern South America. The species grows to about 8 cm and has a very slender, almost scaleless, yellow-brown body with small barbels and spinelets on the gill cover. As a nocturnal bottom-dweller it creeps and wriggles among gravel, sand and stones of mountain streams and snaps at insect larvae and small invertebrates. The fish is harmless to humans.
