Size 79mm or 3.1" 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.

When first described, Pellegrin remarked that compared to other Ancistrus (known at the time), this species has relatively larger eyes, a wider head, fewer interopercular odontodes, and a flatter body profile. Body color is overall brown above, white below.
Sexing Both sexes posses soft tentacles at adulthood. In the male they are typically thicker and often branched.

Hop to next section Husbandry Information
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.
Breeding Reports There is no breeding report.
