API 7 Day Pyramid Fish Feeder
The Pyramid Fish Feeder will automatically feed your fish when you’re on vacation. Features a patented secret chamber containing tubifex worms which opens half-way through the feeding cycle. Will feed 20 average sized fish in a 10 gallon tank for 7-10 days. For freshwater or saltwater fish
After being placed in the tank, the pyramid will start dissolving immediately and the first food pellets will be released within a few hours. Worms are released on about the 4th day. Do not use in fishbowl’s or aquariums without adequate filtration and aeration, because water circulation is needed for the pyramid to dissolve properly.
