Maintain a clear and balanced aquatic environment while keeping your betta entertained with Aqueon PURE Betta Beads product. These innovative beads contain beneficial bacteria and enzymes that eliminate organic sludge in unfiltered aquariums for better water clarity. These soft balls create a fun enrichment activity for bettas while also encouraging their natural foraging behavior. Watch your betta play in the beads like a fun ball pit as they dive in and out.
