How long does the food keep after opening?

Please ensure you buy a packaging size suitable for your aquarium/terrarium/pond so that the quantity contained is used up within 4 months. Compare it with a tin of biscuits lying around for several months. When properly stored they are not necessarily soggy, but they are not quite as tasty as when the packet was opened. Therefore it is not advisable to use the food after this time.

The repeated opening and closing of the packaging brings the food into contact with bacteria and humidity over a longer storage period. Thus the quality of the premium food reduces continuously and this influences the vitamin content and the freshness of the food. For the benefit of your animals you always should feed them fresh food.
