These feeders, made from Styrofoam and cotton, are perfect to feed Microworms to your fish.
Styrofoam feeders float at the water surface, making it easy for you to reach.
The worms will make their way through the cotton and slowly fall to the bottom over a longer period of time.
This gives the fish more time to pick the worms up & they will soon stay close to the feeder, not to miss a meal. Replace the cotton ball when it becomes brown/ sludgy.
