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 literally means heavily-armed(hoplon=heavily-armed) chin(genys=chin) and refers to the fringe of soft tentacles around the edge of its snout.

Size 160mm or 6.3" 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.

The rusty reddish orange fin rays are the key to this attractive species, but this feature does diminish with age.
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.

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 Unreported.
