The beneficial bacteria aids in maintaining a balanced environment while the enzymes help breakdown organic sludge for better water clarity. These soft biodegradable 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. Replace the beads monthly and remove uneaten food for optimal results. If betta beads shrink prematurely, this is a quick indicator that the water hardness is not optimal for your betta. We recommend changing the water with soft (deionized or specially filtered) betta waters.
