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.

This species has dark fins and a network head pattern giving way to regular stripeds along the flanks of the fish. Overall the colouration is reminiscent of adult male Corydoras napoensis.
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.

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. User data.
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.
