Synchiropus picturatus
Family: Callionymidae ยท Dragonets & Mandarinfish
Also known as: Picturesque Dragonet, Spotted Mandarin, Psychedelic Mandarin, Target Mandarin, Picture Dragonet
The Spotted Mandarin Dragonet is the equally mesmerizing cousin of the more commonly seen Green Mandarin, distinguished by its breathtaking pattern of vivid green, blue, and orange spots ringed with dark outlines on a blue-green base color. Rather than the swirling, psychedelic lines of the Green Mandarin, the Spotted Mandarin displays a series of discrete, eye-like spots and rosettes that give it an almost painted or tattooed appearance. This pattern has earned it the alternative name Picturesque Dragonet.
Like its close relative, the Spotted Mandarin Dragonet is a bottom-dwelling micro-predator that spends its days methodically picking tiny copepods, amphipods, and other microfauna from the surfaces of live rock and rubble. It shares the same challenging feeding requirements that make all mandarins difficult to maintain โ a mature, well-established aquarium with a thriving population of live copepods and amphipods is absolutely essential. The Spotted Mandarin is generally considered slightly more delicate than the Green Mandarin, and ensuring an adequate food supply is even more critical for long-term success.
The Spotted Mandarin Dragonet secretes a bitter, toxic mucus coating that provides natural protection against parasites and diseases such as marine ich and velvet. This same coating makes it distasteful to most predators. Despite this natural armor, the fish is slow-moving and docile, making it vulnerable to aggressive tankmates that may outcompete it for food. A refugium connected to the display tank that continuously produces copepods is strongly recommended. Captive-bred specimens are occasionally available and are significantly easier to maintain, as they are more willing to accept prepared foods.
The Spotted Mandarin Dragonet feeds almost exclusively on tiny live copepods and amphipods. A mature aquarium with abundant live rock supporting a healthy microfauna population is essential. Supplement with live copepod cultures such as Tisbe and Tigriopus added regularly to the tank. Captive-bred specimens may accept frozen cyclops, baby brine shrimp, and small mysis shrimp. A refugium producing a continuous supply of copepods greatly improves survival rates. Feed multiple small portions throughout the day if accepting prepared foods.
The Spotted Mandarin Dragonet is one of the most peaceful marine fish available and poses no threat to any tankmates, corals, or invertebrates. Males are territorial toward other male mandarins and should be kept singly unless a confirmed male-female pair is established. Avoid housing with aggressive feeders such as dottybacks, wrasses, or active damsels that will outcompete the mandarin for food. Ideal companions include other slow, peaceful species such as seahorses, pipefish, and small gobies.
Check CompatibilityLike the Green Mandarin, Spotted Mandarins perform a nightly courtship dance at dusk. The male displays his extended dorsal fin to attract the female, and when ready, the pair rises belly-to-belly from the substrate to release eggs and sperm simultaneously at the peak of their ascent. Eggs are pelagic and hatch within 24-36 hours. Larvae are extremely tiny and require phytoplankton-enriched rotifers for the first weeks of life. Captive breeding has been achieved but remains challenging.
