The bright orange color comes from astaxanthin at 120 ppm, which shows up in your fish and corals as deeper reds and oranges. At roughly the size of a large brine shrimp it suits small-mouthed fish such as anthias, dragonets, wrasses, clownfish and cardinals, LPS corals like Goniopora, Duncans and blastos, and freshwater favorites like bettas, discus and angelfish.
