Abstract
An aquarium stick-on liquid crystal thermometer with visual temperature indicator to be viewed through a first wall of an aquarium and including a transparent layer of adhesive over the temperature indicator for attaching the visual material in airtight connection to the exterior of a second wall of the aquarium. The temperature indicators are then viewed through the aquarium water and the aquarium walls. Because of the airtight coupling of the thermometer, the temperature indicators appear clear, bright and distinct when viewed.
