An automatic feeder for tropical fish comprises a rotatable container containing granular feed and a driving device for rotating the container only at preselected times to discharge a predetermined amount of feed from the container. A switch turns on a drive motor at the preselected times to rotate the container, and a pre-settable timer controls the actuation of the switch. The container has a rectangular shape and is divided into a feed-receiving portion and a feed-discharge portion which communicate with each other through an adjustable opening. Rotation of the container through one revolution causes a predetermined amount of feed to flow from the feed-receiving portion through the opening into the feed-discharge portion for discharge from the container. |
