Penn-Plax Daily Double II Battery-Operated Automatic Fish Feeder

GREAT FOR VACATIONS & HOLIDAYS: The Daily-Double II Automatic Fish Feeder is the perfect solution for aquarists who want to make sure their fish are fed during a weekend trip, a vacation, or a holiday stay. The large capacity food drum holds enough flake food for up to 4 weeks! FEEDS TWICE A DAY: This battery-operated fish feeder cycles through 12-hour intervals the moment a battery (AA) is installed. In other words, this feeder automatically feeds fish twice a day. Please note that this is a preset setting, and cannot be changed or altered. Please Note: Battery Not Included. FLAKE FISH FOOD: The Daily-Double II Automatic Fish Feeder is designed to dispense finely crushed flake food. Larger flakes should be broken up to prevent clogging. If you wish to try pellet food, fill the drum only to 1/3 capacity, and check regularly for proper rotation. KEEPING MOISTURE OUT: To keep food dry, do not place above any bubbling aquarium accessories, such as air stones, aerating ornaments, or turbulent filters. The moisture created by these accessories may be absorbed by the flakes, causing unnecessary clogging. ADDITIONAL FEATURES: This feeder can be either mounted to a tank or can be freestanding on top of an aquarium cover or lid. In addition, there’s a built-in adjustable food dispenser that allows you to regulate the quantity of food your fish are receiving.
