Abstract
An automatic aquatic food and water delivery device for supplying food and water to living creatures in an aquarium over an extended period of time including a reservoir positioned above the water line of an aquarium. A mixture of water and food is stored in the reservoir in a predetermined ratio. The reservoir has a sealable intake port for receiving food and water, and an outlet port through which the food and water mixture is delivered to an aquarium. An air supply is disposed within the reservoir and oriented generally towards the outlet port to prevent blockage of the outlet port. A delivery line is attached to the reservoir and an adjustable valve is positioned in the delivery line to control the flow rate of the food and water mixture into the aquarium.
