Smart design for 4 feedings per day: You can set up to 4 feedings at different times at 3 revolutions of the feeding drum. Feeding is possible at any time using the "manual feeding button". Large capacity and versatility: The 200 ml automatic feeder will hold enough food to feed your fish when you are away from home. Easily control the amount of food given to fish by setting a slider to increase or decrease the amount of food per turn. The aquarium feeder is suitable for feeding many types of fish food, such as flakes, granules, powder, strips, etc. The lining stays dry at all times: The opening of the food bucket rotates again after each feeding, which prevents moisture from increasing and food debris from sticking together. We recommend pellets and flakes. Two different installation options: Automatic feeders can be attached to both open and indoor aquariums. During the attachment, the machine can also rotate 360. ① Installed on the base. ② Attach it to your aquarium with double-sided stickers. Make sure the feeder is fixed above the water and cannot fall into the water, get wet or clogged to keep the fish food dry.
