A food dispenser for a fish tank has a funnel shaped container (2) filled with the dried food, with an arm (7) passing through its outlet, which is swung by the fish from below the water level. This arm also passes through a horizontal sliding plate (5) with a pear shaped hole (6) which delivers a measured amount of food. This plate has a slot (15) through it for a screw fitted with a butterfly nut (14) for guiding the plate. The swinging arm (7) hooks onto an overhead suspension strip (9) with alternative hooking holes (8) through it. The slot (15) can be marked with a set of graduations. |
