|Common Name||Bristlenose Catfish|
|Type Locality||Quebrada Cramalote, Barrigona Villavicencio, Colombia.|
|Pronunciation||an SISS truss - try RAID ee ah tuss|
|Etymology||The name Ancistrus is derived from the Greek word agkistron, meaning hook, in reference to the interopercular odontodes that are hooked. This specific epithet refers to the three (tri=three) rays (radiatus=rays) or divisions of tentacles on its snout.|
|Size||120mm or 4.7" SL. Find near, nearer or same sized spp.|
|Identification||Mature males and sometimes females have soft tentacles (bushy fleshy growths) on the snout - this is unique to the genus Ancistrus.
A. triradiatus is an overall mottled brown that can range from golden to dark brown. The caudal and paired fins sport a pattern of darker markings that often merge to form wavy lines.
|Sexing||Typical for the genus with males possessing the so-called ''bushy nose''. Females also may have much smaller growths on the head but to a much lesser extent.|
|Distribution||Exported in large numbers via Villavicencio, Colombia for the aquarium hobby. Most likely occurs throughout the upper Rio Meta and in the lower reaches of Andean streams that feed the Rio Meta. Records from the Rio Magdalena and Maracaibo basin drainages are suspect.
