The Mandarin Goby, more accurately referred to as the Mandarin Dragonet or simply Mandarin Fish, belongs to the genus Synchiropus. This fish is one of the most strikingly beautiful marine species available to aquarists, but it is also one of the most challenging to keep due to its specific dietary needs. Here’s an overview:
- Appearance:
- The Mandarin Dragonet is renowned for its dazzling, psychedelic coloration. It has a base of blue or green with intricate patterns of orange, yellow, and sometimes red. Two of the most common species are the Green Mandarin (Synchiropus splendidus) and the Spotted Mandarin (Synchiropus picturatus).
- Size:
- They typically reach a size of about 3 inches (around 7.5 cm).
- Natural Habitat:
- These fish inhabit the Pacific Ocean, particularly around the Philippines, Australia, and Taiwan.
- Tank Requirements:
- A tank of at least 30 gallons (around 113 liters) is recommended, though larger is better. This is because Mandarins need a substantial amount of live rock to hunt for their natural prey, tiny crustaceans called copepods.
- A well-established tank with a thriving population of copepods is crucial for their survival, as many will not take prepared foods.
- Diet:
- This is where the main challenge of keeping Mandarin Dragonets lies. They primarily feed on small crustaceans, especially copepods and amphipods. In captivity, getting them to accept prepared foods like frozen or live brine shrimp or mysis can be a task.
- It’s essential to ensure that the tank has a robust and sustainable copepod population before introducing a Mandarin.
- Temperament:
- Mandarins are peaceful and often reclusive. They can be vulnerable to bullying by more aggressive tankmates.
- Reef Compatibility:
- They are an excellent choice for reef aquariums. They don’t bother corals and can be fascinating to watch as they hunt for copepods among the live rock and corals.
- Care Level:
- Difficult. While they are not demanding in terms of water parameters, their specific dietary needs can make them a challenge for even experienced aquarists.
- Lifespan:
- In captivity, with proper care, they can live up to 10-15 years, though 3-5 years is more common due to dietary challenges.
- Tankmates:
- Choose peaceful community fish. Aggressive or overly active fish can outcompete the slow-moving Mandarin for food and may also stress or harass them.
The Mandarin Dragonet’s unparalleled beauty makes it a coveted fish for many aquarists. However, its unique dietary needs mean that only those prepared to meet its specific requirements should attempt to keep one. If you’re considering adding a Mandarin to your tank, it’s essential to research thoroughly and ensure you can provide the necessary environment for it to thrive.
