This helps maintain consistent feeding routines even when you're away or pressed for time. 2) Adjustable food dispensing An adjustable slider controls the amount released per rotation, with six levels to suit different fish species and dietary needs. This enables precise portioning to help prevent overfeeding or underfeeding. 3) quality material Made from durable plastic, the feeder offers reliable performance and longlasting use in an aquatic environment. Its sturdy construction supports worry feeding for your aquatic pets. 4) Multiple feeding containers Includes two interchangeable food boxes: a large 210 ml container and a smaller 100 ml option, accommodating a range of food types and portion sizes to fit your aquarium requirements. Use scenarios Vacation or busy days: Set the feeder to dispense meals automatically on a 12 or 24hour cycle, ensuring your betta or other smalltank fish are fed consistently while you're away. Mixed diets or multiple fish: Use the sixlevel adjustable dispenser to tailor portions, and switch between the 210 ml and 100 ml containers to fit different foods and feeding schedules. Manual feeding flexibility: When you want to feed immediately without changing the programmed schedule, use the manual mode to supplement regular feeds.
