The automatic feeder provides a large 150 ml food supply and is designed for feeding granules of different sizes. The food amount per feeding event is adjusted steplessly with a dosage adjuster. This allows feeding meals equally in small aquariums as well as in larger, well stocked tanks. The sera XS-Feeder is also suited for terrarium use, e.g. for feeding young terrapins.

Programming is very simple: the first feeding time is set automatically when switching on the automatic feeder. A second feeding per day is possible if desired. This will automatically follow 5 hours after the first feeding. This ensures two feedings are possible even in case of short lighting times.

The automatic feeder can be installed on top of a hood with the included pedestal, or it can be mounted to the glass of an open aquarium with the also included holder bracket. The XS-Feeder is operated with two 1.5 V size AA batteries (not included).
