Green Mandarin (Synchiropus splendidus)
Description
The Green Mandarin is a show-stopping marine fish prized in reef aquariums for its vivid coloration and graceful movements.
Appearance:
The Green Mandarin features a dazzling palette of green-blue body tones, accented by swirling patterns of orange, blue and sometimes red. These bright hues make it a standout addition to any display. It typically grows to around 3 inches in length.
Behavior & Lifestyle:
This fish is a bottom-dweller, often seen crawling gently over live rock and picking at hidden crevices. It moves with a delicate, flowing motion, and adds lively, natural activity to a reef setup.
Care Requirements:
-
Tank size & environment: A mature, well-established reef tank with lots of live rock, caves and a soft, sandy substrate is ideal. The Green Mandarin thrives when there are many hiding spots and micro-habitats for foraging.
-
Diet & feeding: This species feeds primarily on live copepods and other tiny benthic invertebrates; in the wild it continually picks at the substrate. While some individuals may adapt to frozen or prepared foods, many remain picky and require a steady supply of live-food prey.
-
Reef compatibility: Generally considered reef safe, the Green Mandarin coexists well with corals and many invertebrates when placed in a suitable environment.
-
Difficulty level: Due to its specific dietary needs and habitat requirements, this fish is best suited for intermediate to experienced reef keepers.
Why it’s a great addition:
-
Visually striking — its bright and contrasting colours make it a focal point in any aquarium.
-
Adds natural foraging behaviour and life to the lower levels of the tank.
-
Enhances biodiversity and interest in a mature reef system.
Important to note:
-
Ensure the tank is mature and has a robust population of copepods before introducing this fish.
-
Monitor feeding behaviour closely — a mandarin failing to forage indicates the need for additional live-food supplementation.
-
Be patient — acclimation may take time, especially if the fish is being offered frozen/pellet alternatives for the first time.
