ABSTRACT:
A cover for an animal tank is provided having oppositely outwardly facing hooks thereunder. One of the hooks is fixed in position on the underside of the frame, and the other hook is mounted to the bottom of a slide, which is slideably mounted underneath the frame. When the cover is placed on an animal tank and the lock plate slid outwardly in the frame and the frame is slid in the opposite direction on the top of the tank, the oppositely outward facing hooks engage underneath the interior peripheral shelf of the rim of the tank, securing the cover to the tank.
