A feeder for dispensing food in a fish tank has a feed box for holding fish food and a rotary drive for rotating the feed box to dispense the food. The feed box comprises a container and a cover. The cover has two opposed elastic arms releasably engageable with the container to detachably couple the cover to the container. The rotary drive has two opposed elastic arms inserted between those of the cover and releasably engageable with the cover to be detachably couple the container to the rotary drive. During detachment of the container from the rotary drive, the arms of the rotary drive restrict disengagement of the arms of the cover from the container thereby preventing accidental detachment of the cover from the container. |
