<p>Dual-capacity feeding box optional - 100/210 ml: The large-capacity 210 ml feeding box can hold 100 grams of fish food, and the small-capacity 100 ml feeding box can hold 52 grams of fish food. Choose the right feeding box according to your outing plan, and provide your fish with sufficient food when you go out.</p> <p>Manual or automatic feeding: The automatic feeding mode allows you to reasonably set the feeding time, feeding once every 12 hours or every 26 hours, which is convenient for you to automatically feed when you are on vacation or on a business trip. At the same time, one-button manual feeding will not affect the preset time.</p> <p>Two installation methods: For open aquariums, fix the feeder with a clip and install it on the glass wall of the aquarium; for closed aquariums, fix one end of the Velcro to the aquarium cover and the other end to the base of the feeder, and then stick it. Fix the two ends together. (Note: When using Velcro, you must first wipe the surface, then stick it, and finally install the feeder.)</p> <p>Food type selection: This timer feeder is only suitable for dry food. Perfect for pellets, strips and flakes. Place it above the upper fish tank to protect the food from moisture. Then cover the fish tank lid, leaving only one hole. Plant some aquatic plants in the hole, put the food in this hole, and the fish will come to eat.</p> <p>Use 4 AA batteries (not included): To clean the food box, just take it out, rinse it thoroughly with warm water, and then clean the inner cylinder. Make sure the inner cylinder is completely dry before adding food.</p>
