The aquarium fish tank automatic feeder can be set to feed steadily and quantitatively, allowing you to leave with peace of mind without worrying about feeding. The device has improved moisture resistance, helping to maintain the freshness and dryness of fish food even when water vapor is present in the aquarium. The dispenser discharge port is adjustable and suitable for various types of fish feed, including pellet, particle, flake, and small strip feed. Choose an appropriate feeding container based on your aquarium's needs to avoid frequent refills, food accumulation, and moisture issues. The fish feeder comes with a fixed clip suitable for open aquariums and a Velcro mount for closed aquariums. The clip can also be used to secure water pipes.
