Device for dispensing food to fish in aquariums, composed of a casing inside which there are areas successively in communication with one another vertically, since inside the casing there is a series of shelves attached alternately to two of the opposing side faces of the actual casing, thereby forming a series of cascades that causes the water and therefore the food to run from one shelf to the next. The dispensing device is partly submerged in the water, with its upper part projecting out of the water, with the food being deposited on the shelf in the upper part and, by means of impulsion of water using a pump, said food will be moved from one shelf to the next, alternately, towards an outlet in the zone underneath the lower shelf.
