SeAquarium’s Coralfood is designed for filter feeding species e.g. corals & other inverts such as sponges, tunicates, feather dusters, clams, anemones etc. It’s small particle size means it is also ideal for shrimps & marine fry. Coralfood is specifically formulated to be easily digested by replicating the snow-like maelstrom of food found on a coral reef. For seawater use only. Calculate aquarium capacity: For litres – (L x W x D) in cms and divide by 1000. Allow for water displaced by gravel, rocks etc. Feeding Guide: Use 3 to 4 times per week.
