Abstract: A fish feeding apparatus for disbursing fish food within one or more fish tanks. The apparatus includes a food canister having an opening which is sealed by a removable cap, an array of apertures from which fish food is disbursed, a suction device which enables the food canister to be affixed to an inside surface of a fish tank, and an inlet port whereby a fluid flow is permitted to enter. The apparatus further includes a pump having an outlet port whereby fluid flow is permitted to exit and a section of tubing connected at one end to the outlet port of the pump and at the opposite end connected to the inlet port of the food canister. The cap is removable to exposed the opening in the food canister where large aggregates of fish food, such as flakes or frozen cubes, are inserted. With the cap replaced the food canister is mounted in the fish tank with the array of apertures submerged below the water level.
