Plecos & L-Numbers: The Armored Jewels of the Amazon

Discover our curated selection of Loricariidae, ranging from the hardworking common bristlenose to the ultra-rare "L-Number" species highly coveted by collectors. Unlike standard aquarium fish, many of these "armored catfish" are identified by the L-number system—a classification used by hobbyists and scientists to identify unique species from the Amazon basin that have yet to receive a formal scientific name.
