Abstract- This paper proposesthe design of Smart Fish tank: An IoT-based Aquarium System. The Fish owners ofthe fish are usually when they are away from home because they could not feedtheir fish on time. So we design a Smart Fish tank system using microcontrollerand Arduino based android application to overcome this problems. Through thissystem owner can feed their fish on time and can change water on a time. Also,the user can set schedules for feeding the fish through the solenoid valve andchanging the water thought the relay time.
