Mandarins - Synchiropus splendidus - are one of the prettiest fish in the reef. Slowly moving over the rockwork, they seek 'pods' to eat. It is mandatory that the tank be established for 6 months first, and have at least 75lbs of LR to support this fish's diet. A refugium provides excellent breeding grounds to provide even more food for this delicate creature. Mine have been observed eating prepared foods (frozen or dry) which assures their continued health. They should look fat. Reef-safe.
