Product Description
The Common Bristlenose Pleco (Ancistrus cirrhosus) is one of the most popular freshwater algae-eating catfish in the aquarium hobby. Known for its bristled face (especially in males), hardy nature, and manageable size, it is an excellent addition to community aquariums and planted tanks.
This species is highly effective at grazing on algae and biofilm across glass, driftwood, and décor. Unlike larger common Plecos, the Bristlenose remains a suitable size for home aquariums while still providing strong algae control and a unique appearance.
