All mandarins and their relatives in the scooter blenny's are dragonets, although they are often refered to as goby's. Known as both one of the most popular marine fish and one of the highest rated death's in the hobby, the mandarins are quite an odd but fascinating addition. Their only major food substance is the live copepods and amphipods found on very well established live rock, at least 6 months, preferably more. Some report that they can be fed brine, but only under ideal conditions will they be able to capture them. A pretty good choice for an appropriate setup, but a horrible one for anything but.
