A pellet and flake aquarium fish feeder allows a fish keeper to conveniently feed aquarium fish. The pellet and flake feeder includes a body having separable upper and lower portions. The upper portion includes a cavity for storing the pellet and flake food and a plunger shaft including indented rings. When the pellet and flake feeder is filled with pellet and flake food and assembled, the plunger may be depressed forcing the pellet and flake food through a conical passage between the upper and the lower portions, grinding the pellet and flake food and releasing the ground food through an angled bottom of the lower portion and into aquarium water.
