Green Mandarin Dragonet

Green Mandarin Dragonet (Synchiropus splendidus) is native to Indo-Pacific reef ecosystems. Wild populations distribute across coral reefs from East Africa through Indonesia, the Philippines, and into the western Pacific. Captive-bred Green Mandarin Dragonet is increasingly available and is the more sustainable choice when you can find it.

Green Mandarin Dragonet requires a minimum of 30 gallons for healthy adults. The minimum is based on 3 inches adult size and territorial range. For Green Mandarin Dragonet, plan a mature reef tank with stable parameters, sand bed, live rock for cover, and reef LED if photosynthetic.

Green Mandarin Dragonet requires standard reef parameters: temperature 76-80°F, specific gravity 1.025, pH 8.1-8.4, alkalinity 8-9 dKH, calcium 420-450 ppm, magnesium 1300-1400 ppm, ammonia + nitrite 0 ppm, nitrate under 10 ppm. Use a refractometer (not hydrometer) to measure salinity.
