ABSTRACT:
A fish-actuated aquarium feeder is disclosed wherein a valve having a downwardly extending actuator rod is pivotably supported within a housing that is fastened to the wall of the aquarium. The upper surface of the valve is substantially dome-shaped with the periphery thereof including a series of circumferentially spaced-apart radially extending grooves. An inverted cannular container rests on the top of the dome-shaped valve surface to form a substantially closed storage chamber for fish food with the peripheral grooves lying outside the downwardly facing opening of the container when the valve is in its equilibrium position. When the fish deflect the actuator rod in the proper direction, the valve is rotated from the equilibrium position and permits a small portion of the fish food to fall downwardly into the water. Replaceable washer-like discs that form the contact region between the valve and the housing permit the force required to actuate the feeder to be established for properly feeding fish of various species and size.
