Mandarin Dragonets
The Mandarin Dragonet, commonly called the Mandarin Goby, is one of the most spectacularly coloured fish in the marine aquarium hobby. Its psychedelic combination of electric blue, turquoise, orange and green creates intricate patterns unlike almost any other reef fish.
Despite the common name, the Mandarin Goby is not actually a true goby. It belongs to the dragonet family and spends most of its day slowly exploring live rock and the substrate in search of tiny crustaceans.
Mandarins are exceptionally peaceful and reef safe, making them excellent inhabitants for established reef aquariums. However, their specialized feeding requirements are extremely important. In nature, they continuously hunt copepods and other tiny microfauna throughout the day, so a mature aquarium with a healthy, sustainable pod population is highly recommended.
Some individuals can be conditioned to accept frozen mysis, enriched brine shrimp and other prepared foods, but prepared food should not automatically be assumed to replace a healthy supply of natural prey unless the individual fish is reliably eating and maintaining good body condition.
Mandarins are slow, deliberate feeders and should not be housed where aggressive or extremely competitive tankmates prevent them from getting enough food.

✨ Interesting Fact: Mandarin Dragonets produce a protective slime coating rather than relying on typical fish scales. This mucus helps protect their skin and is one reason mandarins have such a unique texture and appearance.
⚠️ Feeding Note: A Mandarin should never be purchased simply as a decorative fish for a new aquarium. Long-term success depends heavily on providing enough food, whether through a thriving copepod population, reliable prepared-food feeding, or a combination of both.
