Essential Information:

• Common Names: Green Mandarin Goby, Mandarin Dragonet, Psychedelic Goby
• Scientific Name: Synchiropus splendidus
• Family: Callionymidae
• Origin/Habitat: Western Pacific, including the Philippines and Australia; typically found in sheltered lagoons and inshore reefs.
• Maximum Size: Up to 4 inches (10 cm) in length.
• Lifespan: In captivity, they can live between 2 to 5 years with proper care.
• Level of Difficulty: Advanced; requires specialized care, particularly concerning diet and habitat conditions.

Appearance & Physical Traits:

• Coloration & Pattern: Displays a kaleidoscope of colors, including vibrant blues, greens, oranges, and yellows, arranged in intricate, wavy patterns across the body and fins.
• Body Shape & Structure: Small, elongated body with a broad head and protruding eyes; lacks scales, giving it a smooth appearance.

Habitat & Environmental Needs:

• Minimum Tank Size: A well-established aquarium of at least 30 gallons (114 liters) is recommended to provide sufficient live rock and microfauna.
• Water Temperature: Maintain between 72°F and 78°F (22°C to 26°C).
• pH Level: Keep between 8.1 and 8.4.
• Specific Gravity: Optimal range is 1.023 to 1.025.
• Aquascape: Provide ample live rock with abundant hiding spots and surfaces for natural prey (copepods) to thrive; a mature refugium can help sustain food populations.

Diet & Feeding:

• Diet Type: Carnivorous
• Preferred Foods: Primarily feeds on live copepods and other small crustaceans; may accept live brine shrimp or specially prepared frozen foods, though transitioning can be challenging.
• Feeding Frequency: Requires continuous access to food sources due to a high metabolic rate; multiple small feedings throughout the day are ideal.

Behavior & Compatibility:

• Temperament: Peaceful and non-aggressive; spends much of its time hovering near the substrate searching for food.
• Social Behavior: Can be kept singly or as a mated pair; males may exhibit aggression towards other males.
• Tank Mate Compatibility: Compatible with other peaceful species; avoid housing with aggressive feeders that may outcompete them for food.
• Activity Level: Relatively sedentary, with slow, deliberate movements; often observed perching on rocks or substrate.

Care Considerations & Additional Notes:

• Ease of Care: Challenging due to specific dietary needs and sensitivity to water quality; best suited for experienced aquarists.
• Special Requirements: A well-established tank with a robust population of copepods is essential; consider periodic supplementation to maintain food sources.
• Breeding Info: Breeding in captivity is rare but possible; involves complex courtship behaviors and external fertilization.
• Additional Notes: Due to their specialized care requirements, potential keepers should thoroughly research and prepare to meet their needs to ensure long-term health and well-being.
