Abstract: An aquatic viewing system is described for enabling a person to see magnified images of marine life contained in an aquarium. The system includes a magnifying lens and mounting attachment attached to the periphery of the lens. The mounting attachment is adapted to be detachably mounted to a transparent face of the aquarium. The lens may be moved to any desired viewing location on the aquarium by detaching the mounting attachment from the face of the aquarium and re-positioning the mounting attachment and lens at the desired viewing location.
