Ancistrus leucostictus

Ancistrus leucostictus is a peaceful species that is active mainly in twilight when it gets a bit darker inside your aquarium.


Ancistrus leucostictus

Ancistrus leucostictus has been officially described by Günther in 1864. The name Ancistrus is derived from the ancient Greek “agkistron” which means hook as a reference to the interopercular odontes (the bristles on their snout) that are hooked. The species name leucostictus comes from two ancient Greek words: “leukos” meaning white and “stictus” meaning spotted.

Synonym: Chaetostomus leucostictus


Ancistrus leucostictus is a peaceful species that is active mainly in twilight when it gets a bit darker inside your aquarium. Use lots of plants and wood to create shelter and hiding spaces. Add some suitable caves to make make them more comfortable. They can grow up to 13 centimeters total length but their territorium is not that big. You will need an aquarium of 80 centimeters to keep one male with one or more females.

The males develop bristles on their snout which sometimes can also be found with the females. These bristles grow larger as the male ages. The female usually has none or very small bristles.


South America; Brazil, Guyana.


The main diet of the Ancistrus leucostictus should consist of vegetable matter. Feed them herbivore tablets and plant matter like lettuce, cucumber etc.

Breeding Ancistrus leucostictus

Males create a territory in and around a cave. They prefer caves where a female just fits in. Towards other males they can be a bit aggressive when fighting over the best cave, especially when kept in a too small aquarium or when there are not enough suitable caves.

The Ancistrus leucostictus female lays the eggs that are fertilized by the male. The male guards the nest and fans the eggs. After four to five days the yellow eggs hatch. The fry stick around the cave for quite some time.


The real Ancistrus leucostictus mainly originates from Guyana. As Guyana is not exporting fish for the aquarium trade you will not likely find this species at your LFS. If you do it is likely you will get another more common Ancistrus species.
