Synchiropus picturatus
Small goby with psychedelic green body covered in orange spots with black borders. Prefers live copepods, so mature live rock tanks are ideal.
The spotted mandarin (Synchiropus picturatus) is a small dragonet of the family Callionymidae found in the western Pacific. Its psychedelic coloration, a green ground sprinkled with black-ringed orange and blue spots, is its greatest appeal. Lacking scales, it protects itself with body mucus, which makes it relatively resistant to parasites such as ich, though it is vulnerable to injury and medications. It is a specialist feeder that subsists chiefly on tiny live foods such as copepods, so it is ideally kept in a mature aquarium rich in live rock and microfauna. Slow-moving and peaceful, it offers great visual interest as it creeps along the bottom.
