The Blue Tip Frogspawn Euphyllia Coral is a large polyp stony coral (LPS) often referred to as the Wall, Octopus, Grape, or Honey Coral. Its primary nutrition from the symbiotic zooxanthellae living within its tissues. However, we still do recommend you do supplemental feeding by adding mysis and brine shrimp. Its polyps remain visible throughout both the day and night, resembling a mass of fish eggs or frog eggs, hence one of its common names Frogspawn. With its appearance and coloration it would make a nice addition to any reef aquarium.
