Species Profiles
Bristlenose Pleco
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.

Assassin snails are the natural pest snail control solution. They hunt and eat bladder snails, pond snails, Malaysian trumpet snails, and ramshorn snails. They breed slowly (unlike pest snails), have attractive yellow and dark brown striped shells, and are safe with fish and shrimp.
