Two Little Fishies ChalicePower contains a variety of particle sized concentrated and dried zooplankton designed heavy to sink in the water column. This should be fed directly over the coral, as it imitates their natural suspension-feeding behaviors. This is suitable for all filter feeding invertebrates like soft and stony corals, anemones, feather duster worms, clams, sponges and tunicates or for raising and maintaining chalice corals, including Mycedium, Pectinia, Echinopora, Oxypora, and Echinophyllia. Give your aquarium life the best possible nutrition for a successful hobbyist experience. Developed by Justin Credabel.
