The Common Plec has the potential to grow very large, even if kept in small aquaria. It should be housed in a tank at least 4ft long to start off with, and moved on to larger quarters to give the fish the space it deserves. Often sold as ‘good algae eaters’, these fish will rapidly outgrow the average community aquarium. A better choice of algae-eater for the smaller tank would be Bristlenose catfish (Ancistrus sp.). This species will not harm tankmates, even small sized fishes. Minor squabbles may occur when more than one specimen is housed in the confines of the same aquarium. Larger specimens can be clumsy, knocking over décor, which should, therefore, be chosen very carefully. May also be seen on sale as Pleco, Plecostomus, and Suckermouth Catfish.


Omnivorous, although the majority of the diet should be made up of vegetable matter.


Unlikely in the home aquarium.
