The EHEIM TWINfeeder is an automatic fish feeder featuring two independently programmable food chambers, allowing you to dispense different types of dry food (flakes, granules, pellets or sticks) at set times or via a manual “snack” button. Designed for convenience when you’re away and to maintain consistent nutrition in freshwater or marine aquariums, it also includes a low-battery warning and splash-proof controls to safeguard reliable operation.
