The California Stingray, Urobatis halleri, also known as Haller's Round Ray, is a bottom dwelling ray with a brown body and  yellow spots. It has a poisonous tail and should be treated with extreme care. Generally found in the coastal waters of the Pacific, the California Stingray thrives on benthic invertebrates and is not necessarily reef safe. They will need a tank of at least 300 gallons to provide them enough space and should only be kept by experience aquarists.
