Do plecos eat fish food off the ground?

Plecos are bottom-feeders and will eat food that has settled to the bottom of the aquarium. They will also scavenge for food on the ground, and may eat fish food that has been dropped by other fish. However, plecos should not be fed exclusively on fish food, as they need a diet that is high in plant matter. A good diet for plecos includes algae wafers, sinking pellets, and fresh vegetables.
