【Programmable】: Barkmew Automatic Fish Feeder allows you to set up to 3 automatic feedings per day. You can program it to feed at any hour of the day or night and have it deliver either a single or double or triple feeding. At the same time, you can also feed manually and experience the fun of feeding. 【Easy to Add Food】: This auto fish feeder adopts top opening design for quickly and easily adding feed, so you can easily increase or decrease the amount of food dispensed without taking down the food bucket. Because of the 360°rotation of the pedestal of this automatic fish feeder, you can rotate it to the satisfying position after it is installed. 【Two Different Fixed Methods】: Our fish feeder is designed with 2 install methods to meet different needs. One is to fix the feeder to the tank wall by using the holder. Another is to paste the feeder with double-side sticker on the tank cover.
