The Spotted Mandarin (Synchiropus picturatus) is a peaceful, reef safe fish that requires a well established tank with plenty of live rock and an established pod population. They are best suited for an aquarium of 30+ gallons. They are only aggressive towards their own species, unless a mated pair is formed. Spotted Mandarins are reported to eat small amounts of Red Planaria flatworms. Wild fish often take a while to accept frozen foods. Feed live brine, live pods, and live black worms, while training them to eat frozen foods like Mysis and Brine. Max size is around 3".
