Cat-eLog Data Sheet
Scientific Name	**Ancistrus occidentalis** (Regan, 1904)
Common Name(s)	None
Type Locality	Canelos, eastern Ecuador.
Synonym(s)	Xenocara occidentalis
Pronunciation	an SISS truss
Etymology	The name Ancistrus is derived from the Greek word agkistron, meaning hook, in reference to the interopercular odontodes that are hooked.
Species Information
Size	86mm (3.4") 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.
Sexing	Males develop soft tentacles on the head.
Habitat Information
Distribution	South America: Bobonaza River basin. Amazon, Upper Amazon, Marañón, Pastaza, Bobonaza (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
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.
