API 7-Day Fish Feed Block is a holiday food block for tropical, coldwater and marine fish. Each holiday block contains real fish food, and automatically feeds your fish when you're on holiday! This product features a patented secret chamber containing Tubifex worms which opens up half-way through the feeding cycle.
Instructions: One pyramid will feed 20 average-sized fish in a 40 litre (9 gallons) aquarium for up to 7 to 10 days, depending on the temperature and pH of the water. 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. Note: in very hard water, the dissolving time may increase. We do not recommend the use of this product in fish bowls or aquariums without adequate filtration and aeration, because water circulation is needed for the pyramid to dissolve properly. Avoid placing the pyramid feeder in the direct flow of the aquarium filter as it may dissolve too quickly.
