Plecostomus catfish, or plecos, are a specialty of Aquarium Fish Sale.  These catfish originate in South America. Since many colors, sizes, and patterns can be found, common names often aren’t enough to identify one pleco from another. So, in 1988, a tropical fish magazine in Germany called DATZ assigned “L” numbers to distinguish species. Although not scientific, the system works.

We carry a few plecos that have not been assigned their L number, but we are sure the Germans will get around to these eventually.

Medium size is 2” to 3”. Most plecos do better with a little driftwood in the tank.
