The Bristlenose Pleco (Ancistrus sp.) is one of the most common aquarium Plecos.
People tend to choose the Bristlenose over the Common Pleco because of their smaller size and they are easier to keep.
One of the main reasons this fish is so common in home aquariums, is because of its useful ability to keep algae down.
The Bristlenose Pleco is known as a number of different names including; Bristlenose Catfish, Bushynose Catfish, Common Bristlenose Catfish and the Brushmouth Pleco.
The Bristlenose Catfish is one of the smallest aquarium catfish, and will grow up to an average of 3-5 inches.
It has a wider head, and is much shorter, fatter and flatter than the Common Pleco.
They have a flattened body covered in bony plates, and as they reach maturity, they sprout tentacle like branches from their head. The males’ tentacles are longer and more prominent than females.
