[Capacity] The capacity of the storage tank is between 165ml and 170ml, about 140g to 160g. The translucent plastic box allows users to easily and clearly see the amount of food remaining in the storage tank, which is convenient for quick replenishment. [Manual button and smart timing] The button can choose two different feeding frequencies: you can choose to feed every 12 hours or once every 24 hours. The blue light flashes when the user is set to feed every 12 hours. When the blue light is always on, it means the fish food will not spoil or block the feeder. 【Input】Particle feed diameter
