20-Pack Bio Sponge Filters For Betta Fry & Small Aquariums - Double Sponge, Size S, Model XY-2831

About This Product

These are fantastic little sponge filters, especially for small tanks, betta fry, shrimp, or hospital setups. You get a pack of 20, so they're super affordable per filter. They're the double-sponge design (size S), which means more surface area for beneficial bacteria to grow, helping keep your water clean and clear. They provide gentle filtration without creating a strong current, which is perfect for delicate fish like bettas or baby fry. Just attach them to an air pump via airline tubing, and they'll bubble away, providing both mechanical and biological filtration. Brand new from XINYOU (model XY-2831). Whether you're a breeder with multiple tanks or just want to keep a small aquarium healthy, these sponges are reliable, easy to clean, and effective. A must-have for any fishkeeper's supply cabinet.
