Abstract: A cleaning device adapted for use in cleaning the interior surface of the glass walls of an aquarium fish tank. The device allows for the interchange or replacement of cleaning elements to accommodate the cleaning of the various types of surface deposits which may be found on the interior glass of the aquarium, by removably attaching the cleaning element to the headpiece of the cleaning device. The preferred embodiment of the invention includes an elongated handle, a non-rusting glass scraper, rigid projections from the headpiece to hold the cleaning element in position during use, and a planter feature for pushing aquarium plants and air tubing under the bottom material in the aquarium.
