The Great Pyramid Feeder - 7 day

Place the 7-Day Pyramid Fish Feeder in your aquarium. It will immediately start to dissolve, giving off a stream of fine bubbles. Within a few hours, the first nourishing food pellets will begin to swell and push out of the pyramid. One pyramid will feed 20 average-sized fish in a 40 litre tank for 7 to 10 days. On or about the fourth day, a secret chamber in the 7-Day Pyramid Fish Feeder will open, releasing a spirulina algae cube for a surprise midweek treat.
