Auto Feeder CupTake the time out of feeding your fish. Feed any size of flake or pellet food from your auto feeder, dispersing equally throughout your entire tank with no chance of going down your overflow. Slow Release: Disperse food over time (2 4 minutes) to make sure even your smallest fish gets well fed. Stay Out of Weir: Food from your auto feeder disperses down below the water's surface, giving no chance for it to go down your overflow filtration weir.
