Description The 4-Way Cone Worm Feeder is made up of three separate pieces: - a floating ring - a cone worm feeder - a suction cup The floating ring may be used to provide dry food while floating on the surface or, when used in conjunction with the suction cup, it may be attached to the side wall of the aquarium to restrict feeding to a certain area. In addition, when inserting the cone, it may be used as a free-floating or confined worm feeder. The 4-Way Cone Worm Feeder is made of a soft, flexible, break-resistant plastic.
