Common Plecostomus 5cm
The Common Plecostomus 5cm is a juvenile algae‑grazing pleco that grows into a large, powerful catfish. While hardy and efficient at cleaning surfaces, the Common Plecostomus 5cm is best suited to big, well‑filtered aquariums with plenty of driftwood, hiding spots and strong filtration to handle its adult size and waste.
