Fluval Bug Bites Bottom Feeder Sticks (4.6 oz) are sinking sticks formulated for herbivorous and omnivorous bottom feeders such as plecostomus and other catfish. With up to 40% insect larvae as the first ingredient and added veggie content (like algae and kelp), these sticks deliver high-quality protein and fiber that support healthy digestion. They soften slowly in water, allowing bottom dwellers to graze naturally, and provide a complete daily diet to promote growth and vitality.
