The link doesn't seem valid, but to answer your question. The Gold Nugget Pleco, species is Baryancistrusxanthellus, attains 240 mm or 9.4 inches. Like all Hypostominae, it produces considerable waste, so this means a large tank. I would consider nothing less than 150 cm/5 feet in length. They are primarily but not totally vegetarian, discernable from the fish's physiology. More info here:
