| The holiday block with real fish food inside! Automatically feeds your fish for a whole weekend. Place the 3-Day Pyramid Fish Feeder in your aquarium and 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 15 to 20 average sized fish in a 40 litre aquarium for 3 to 4 days, depending on the temperature and pH of the water. Suitable for tropical, coldwater and marine fish.
Do not use in fish bowls or aquariums without adequate filtration and aeration, as water circulation is needed for it to dissolve. |
