14-Day 1.2-Ounce Automatic Fish Feeder R1857

The API 14 day feeding block is a complete feed for all tropical, coldwater and marine aquarium fish containing real fish food inside.Each pack contains 4 pyramids. One pyramid block will feed 5-10 average sized fish in a 40L aquarium for up to 14 days. The block 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. Do not use in fish bowls or aquariums without adequate filtration and aeration because water circulation is needed for the pyramid to dissolve properly. Avoid placing it in direct water flow as this may cause it to dissolve too quickly.
