SexingMales develop soft tentacles on the head.
General RemarksIn well over a decade of this site being in operation, all fish seen sold under the name Ancistrus leucostictus are misidentified. French Guyana, where this species comes from, isn't exporting fish for the aquatic trade, and hasn't been for a long time. A common species sold under the name of A. leucostictus is the Ancistrus sp`Rio Ucayali`, but could be any of the commonly available Acnsitrus.

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.
