Two Little Fishies MagFeeder is a magnetically coupled feeding point for aquariums. Use MagFeeder with the included feeder ring to retain pellets, flake foods (including SeaVeggies Seaweed Flakes), powdered invertebrate foods, and other foods that may be dispensed from an automatic feeder. The ring helps prevent floating foods from going to the overflow. It can easily be positioned at various distances from the wall because of the jointed links and magnetic mount attracted to the TLF logo magnet, located outside the aquarium. The entire wet assembly floats if it becomes uncoupled.
