Down Species Information
Size 100mm or 3.9" 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.

See general remarks - this fish is very unlikely to appear in the local fish shop!
Sexing Males develop soft tentacles on the head and while sometimes females also do, it is never to the grand extent of those found on that of the conspecific male.
General Remarks Since at least the 1990s, fish seen sold under the name Ancistrus leucostictus are misidentified. French Guyana, where this species comes from, doesn't export fish for the aquatic trade, and hasn't for a long time. A common species sold under the name of A. leucostictus is Ancistrus sp`Rio Ucayali`, but could be any of the commonly available Ancistrus.

Down 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.
Breeding Reports There is no breeding report.
