Fin's Fish Guide
The Catfish (Ancistrus cirrhosus) is a freshwater fish of the family Loricariidae that grows up to 9 cm.
Description
The bristlenose catfish is an armoured catfish (Loricariidae) from southern South America. The species has a flattened body armoured with bony plates and an inferior sucker mouth; adult males bear a tuft of fleshy tentacles (bristles) on the snout, to which the name refers. It inhabits a variety of waters, from turbid pools over clay to clear flowing water over gravel. With its sucker mouth it scrapes algae and growth from stones and wood. The stout pectoral fin spines and rough armour can give a puncture wound when handled; otherwise the fish is harmless.
