A two-way feeder for use in an aquarium. The feeder has a base that can be buried in sand or crushed coral in an aquarium. One or more fittings on the underside of the base provides a user of the feeder with the option of applying one or more suction cups to the feeder. The suction cups are used to attach the feeder in different surfaces of the aquarium, including the bottom surface and the side walls. The feeder can be used as to attach food in at least two ways. First, buoyant foods such as cucumber can be secured to the top of the device by screwing the cucumber over the head of the threaded receiver. Second, leafy foods such as lettuce or seaweed can be secured by a spring clip associated with an adapter that is compatible with and screwed onto the threaded receiver.
