The Green Mandarin Dragonet, Synchiropus splendidus, features a vibrant green scaleless body with orange and blue wavy lines across the body and tail highlighted in blue edging. Male Green Mandarin Dragonets also have a large pointed dorsal fin. They are very peaceful and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks. However, they are very sensitive and can be difficult to acclimate, requiring an established set up and steady copepod source.

Gobies tend to stay mainly towards the bottom of the tank, burrowing and sifting through the sand. Diet should include a steady supply of amphipods and copepods, and over time can be weaned to a varied diet of frozen or live mysis shrimp and vitamin enriched brine shrimp 1-2 times daily.
