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 7-8 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 4 th 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.
