General Description: The Spotted Mandarin Dragonet, also referred to as the Target Mandarin or Dragonet, is native to Indonesia. While ocassionally these fish may be referred to as gobies, they are not and belong to the dragonet family Callionymidae. Spotted mandarins are extremely popular among hobbyists for their mesmerizing coloration and circular pattern, but having such beauty in the home aquaria does not come easy. Dragonets have specific dietary requirements of live amphipods and copepods, and coaxing a Spotted mandarin to accept frozen-based foods can be challenging. Because of this, Spotted mandarins should not be put into an aquarium that is less than 6 – 8 months old, as this allows their natural, live food source ample time to populate in abundance (see tank requirements for further information about tank-mates that could deplete these resources). Spotted mandarins can be confidently sexed after 1″; males have a more elongated, pointed first dorsal fin compared to females. An adult Spotted mandarin can reach a size of approximately 3″. Note: All of our Spotted mandarins have been through our 28 day quarantine process and are eating a combination of live brine shrimp and frozen foods, in addition to live copepods.
Diet Requirements: In the wild Spotted mandarin dragonets are carnivorous, continuously hunting and feeding on amphipods and copepods in live rock. It is absolutely imperative to have an established tank of at least 6 – 8 months old, and add live copepod cultures (or a live food of equal value) weekly or biweekly to keep this resource available to your mandarin. Spotted mandarins can be extremely stubborn with accepting frozen foods and some may never do so. Offering live adult brine shrimp or black worms can help bridge the transition to small frozen foods. If your Spotted mandarin does eat frozen foods, this does not replace the need for its natural food source (copepods). We highly encourage soaking frozen foods in vitamin and fatty acid supplements for the mandarin’s health and to maintain body mass.
Care Requirements: A minimum 55 gallon aquarium is ideal to house a single Spotted Mandarin; a pair would require more space. In smaller aquariums, the demand of the Spotted mandarin’s feeding behavior becomes more difficult to sustain. This fish cannot be put into a biologically immature aquarium. Dragonets absolutely need generous live rock for feeding and some crevices to take refuge. Male Spotted mandarins will conflict with each other; keep one per aquarum or a single male-female pair. Do not house dragonets with aggressive and pugnacious tank-mates. Fish that will also inadvertently outcompete it for live copepods should be avoided. Examples include, but are not limited to, certain anthias, gobies, dottybacks, wrasses, and basslets. Spotted mandarins are most at home in reef aquariums and they will not harm any invertebrate or coral. Recommended water conditions, 72-78° F, KH 8-12, pH 8.1-8.4, salinity 1.020-1.025.
