Size 100mm or 3.9" SL. Find near, nearer or same sized spp.
IdentificationMature males and sometimes females have soft tentacles (bushy fleshy growths) on the snout - this is unique to the genus Ancistrus.

The overall appearance of this species is not as useful for identification as you may think - there are many Ancistrus species which have a dark base with small white dots as colour pattern. There is however a key that differentiates this species from all other (currently known) Ancistrus species - it's the only species with one hard and nine soft dorsal rays (I,9). Also encountered under the name Ancistrus hoplogenys.
SexingMales have head tentacles, females do not.

Jump to next section Husbandry Information
FeedingAncistrus are omnivorous with something of a vegetarian bent. Vegetables and commercially prepared food are avidly taken. They also like to eat blood worms, gammarus and most frozen foods. You can also witness them eating dead fish when they find a carcass before you do.
FurniturePrefers wood to stone. Bamboo caves are best but will also take refuge in slate or PVC pipes.
CompatibilityWill defend their own territories, but these are small and so groups can be housed in relatively small aquaria.
Suggested TankmatesAppropriate with most community fish that aren't overly big or aggressive.
BreedingReasonably straight forward once the correct (black water) parameters are attained. Spawning follows the typical pattern for the genus. The female lays around 50 eggs in a cave or hole that is guarded by the male.
