The Pleco Feeder's patented design makes feeding your plecostomus fruits and vegetables easy and fun. How it Works To use, simply thread produce or cooked shrimp onto The Pleco Feeder. Then, clip The Pleco Feeder into your aquarium. Your plecos will love eating nutrient-dense foods like butternut squash, cucumbers, and zucchini—and you'll enjoy watching them devour their treat!
