Size 160mm or 6.3" SL. Find near, nearer or same sized spp.
IdentificationMature 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.
SexingTypical 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.

FeedingAncistrus 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.
CompatibilityA 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 TankmatesAppropriate with most community fish that aren't overly big or aggressive.
