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.

To date this species is known solely from the photograph taken by Rainer Stawikowski, which evidently shows a female. It was collected from the lower Rio Araguaia, Pará State and Rio Tocantins. The striking feature of the species is the transparent fin membranes of both the dorsal and caudal fins. Pigment is only shown in the fin rays, which are black with white points.
Sexing Males have large obvious head tentacles, in females they are either very small or non-existent.

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.
