The Colombian blue eyed pleco is a peaceful species, often laying on the bottom levels of the aquarium. Although most friendly, they can become territorial when there are multiple in an aquarium. Their name speaks for itself: they have striking eyes which display a beautiful blue colouration. Adult plecos can reach a length of up to 25 centimeter, so we advise not to keep them in smaller aquariums.
