Vacation Feeder

KB Holiday Food Block is suitable for all coldwater & tropical fish. It is a calcium matrix that slowly dissolves to release fish food into the water, thus keeping your fish fed.
Saves worrying about your fish being hungry whilst you are away on holiday.
 
How to use
Simply place the block into the aquarium and leave it. The block will then slowly release small particles of food when disturbed by the fish looking for food. If any of the food block is uneaten on your return, carefully remove the remains and discard.
