The Ruby Red Dragonet (Synchiropus sycorax) 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. Many people report success keeping groups as long as they are added at the same time, and multiple females per male are present. 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".
