Two Little Fishies PouchFeeder is a magnetically-coupled feeding point for aquariums. Use it to retain SeaVeggies Purple, Green, and Red Seaweed, frozen foods, soft vegetables, or any soft food items so that fish can graze. After inserting the food, simply push the star-shaped hole at the top of the PouchFeeder screen over the head of the Feeder Mount. You can attach more than one screen on the Feeder Mount to offer different types of food, or to reduce the competition between fishes. The entire wet assembly floats if it becomes uncoupled. You can also use the Feeder Mount with the included TLF button to retain ring-shaped food preparations, such as the New Era Grazer. The button stem pops into the socket hole in the mount and can easily be removed.
