Pronouncedan SISS truss
EtymologyThe name Ancistrus is derived from the Greek word agkistron, meaning hook, in reference to the interopercular odontodes that are hooked.
IdentificationMature males and sometimes females have soft tentacles (bushy fleshy growths) on the snout - this is unique to the genus Ancistrus.
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.
TankmatesAppropriate with most community fish that aren't overly big or aggressive.
SexingMales develop soft tentacles on the head.
BreedingAll Ancistrus species are cave-breeders, where the male looks after the eggs and young fry.
SizeSmallest 48mm, largest 250mm, average 110mm, most commonly 100mm. All SL.
