A Temperature Regulated Automatic Aquarium Feeder includes an insulated container, temperature regulating elements, and dispensing elements for the temperature controlled storage and feeding of temperature sensitive foods to aquariums. Temperature sensitive foods such eggs, shrimp, copepods, amphipods, rotifers, or microalgae are placed into an insulated container. The insulated container is heated or cooled by use of temperature regulating elements such as a thermoelectric elements, heat sinks, and electric fans. Food is released through opening of a valve or piston in gravity fed models, or pulled out of the insulated container with a pump in alternative configurations. The schedule of food release is controlled through an automatic timer or digital controller.
