The suckermouth catfish or common pleco, is a tropical fish belonging to the armored catfish family known as Loricariidae. They are named for their armor-like longitudinal rows of scutes (a bony external plate or scale overlaid with horn such as the shell of a turtle or the skin on a crocodile) that cover the upper parts of their head and body.

Plecos have been grouped into families and given Latin names, while some have been given common names such as, zebra pleco, golden nugget, blue phantom, royal whiptail and orange spotted bristle nose. As there are too many to name, experts have tried to classify each species by giving them a unique number, the numbers start with a prefix of L or LDA and are known as the L-number – a pseudo-scientific classification system based on photographs of shipments of plecos.

The various types of plecos differ in size and colour, from mottled brown to black and white stripes and spots as well as yellow, green, orange and red or some even have blue patterns.

There is a common misconception that all plecos eat algae and rubbish in the tank and are therefore purchased to be tank cleaners and do not need to be fed. This is, however, simply NOT true. Some plecos include algae and wood in their diet, some are herbivores, some omnivores and some are carnivores, so they all do need food which is appropriate for them.

As there are so many L-number pleco varieties, please contact us to find out which plecos we have in stock.
