Mandarin fish are probably one of the most beautiful reef-safe fish that are available for hobbyists today. With their graceful meanderings, their colorful markings and gossamer fins, people quickly fall in love with these gentle creatures. Surprisingly, they aren't that expensive, giving the reef keeper even more motivation to acquire one.
There are various types of Mandarins, such as the large blue, red or green Synchiropus splendidus, and the smaller Target or Spotted Synchiropus picturatus. These fish hunt for food all day long, picking at the rockwork for bugs smaller than we can see. At night, they rest. While they rest, their colors fade substantially, so don't worry.
