Ancistrus species list – overview of antenna catfish & L numbers

The genus Ancistrus comprises a large number of described species as well as undescribed forms, which are often known in aquatics by their L numbers. On this page, as many of these Bristlenose Catfish as possible are compiled into a clear Ancistrus species list. Many items include brief profiles with photos, information on origin, and tips on care in the aquarium.

Using the filters, for example, you can display only scientifically described species, exclusively undescribed forms, or specifically the known L-Numbers. This gives aquarists a quick introduction to the diversity of the genus, enabling them to better classify animals from the trade and find suitable literature.

The information in the profiles is deliberately kept concise and is intended to provide an initial overview. Detailed descriptions, further information on biology, many additional photos, and practical experience can be found in the standard work “Bristlenose Catfishes: The Plecos of the Genus Ancistrus“, which is referenced for each species.
