Dragon Wrasse (Novaculichthys taeniourus)
The Dragon Wrasse (Novaculichthys taeniourus) is a dramatic Indo-Pacific marine wrasse known for its remarkable transformation from juvenile to adult. Juveniles display a burgundy-brown body, irregular white markings and elongated dorsal and pelvic fin rays that resemble drifting seaweed, while mature fish develop a powerful body with contrasting dark, pale and greenish markings.
Also known as the Rockmover Wrasse or Reindeer Wrasse, this intelligent and highly active predator spends much of its day turning rubble and searching the substrate for crustaceans, molluscs and other invertebrates. Its adult size, destructive foraging behaviour and increasingly assertive temperament make it a demanding species for aquarium settings.

Bought this for a reef tank, but after a few weeks it started damaging the sand bed and chasing smaller fish. Not suitable for a small or community tank. Only recommend for experienced saltwater aquarists with large, stable setups.
Richard Gill –
The fish looks beautiful when young, but it quickly became aggressive and destroyed coral structures. We had to relocate it to a larger tank. Not a beginner-friendly species.

We kept it in a 120-gallon reef tank with plenty of rock and hiding spots. It’s active and interesting to watch, though it does dig through the sand regularly. Needs a lot of space and careful management.

We were excited by the appearance, but it attacked our shrimp and broke several pieces of rock. It’s too strong and territorial for our tank size. Would not recommend.
