Species Profiles

Ancistrus spp.
beginnerpeaceful20+ gal
The Bristlenose Pleco is the most popular pleco species for home aquariums, and for good reason — they stay small (4–5 inches vs 12–24 inches for common plecos), are excellent algae eaters, and are hardy and easy to care for. Males develop distinctive bristle-like growths on their nose, which is how they get their name.
