Down arrow Species Information
Size 98mm 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.

What is identified as A. temminckii in the aquarium trade and some hobby literature nowadays is possibly A cf. cirrhosus but the true origins of that fish is unclear. The real A. temminckii may have shown up in the trade in the past, but is almost never imported nowadays. A. temminckii can be distinguished from A. cf cirrhosus by the absence vs. presence of a dark spot at the dorsal fin base, between the first and second ray.
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.
General Remarks There are no known type specimens for this fish.

Down arrow 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.
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.
