How Large Can Plecos Grow?

Before you purchase a Pleco, it is a good idea to find out how large that particular species can grow. A small 8 centimetre (3 inches) Pleco from the fish store can eventually turn into a 60 centimetre long (2 feet) fish that needs a very large aquarium to do well.

Different Pleco species will have different colorations, and some of them can also be recognised on special anatomical features. The Bristlenose Pleco (Ancistrus dolichopterus) can for instance be recognised on its protruding “horns”.
