|Scientific Name||Ancistrus variolus (Cope, 1872)|
|Type Locality||Río Ambyiacu, Peru|
|Pronunciation||an SISS truss|
|Etymology||The name Ancistrus is derived from the Greek word agkistron, meaning hook, in reference to the interopercular odontodes that are hooked.|
|Size||48mm or 1.9" 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.|

|IUCN Red List Category||Data Deficient, range map and more is available on the IUCN species page. Last assessed 2014.|
|Feeding||Ancistrus should be fed mainly on vegetarian foods. Prepared foods include algae wafers and spirulina based sinking food. Vegetables such as courgette/zucchini, and (English) cucumber are an excellent addition to the diet, along with the odd, small amount of more meaty foods.|
|Compatibility||A good complement to most aquariums, they are not aggressive to other species. Males may fight over territory if kept in too small a tank.|
|Suggested Tankmates||Appropriate with most community fish that aren't overly big or aggressive.|
|Breeding||All Ancistrus species are cave-breeders, where the male looks after the eggs and young fry.|
|Breeding Reports||There is no breeding report.|
|Reference||Proceedings of the Academy of Natural Sciences of Philadelphia v. 23, pp 288.|
