Overview

The dragon wrasse is an aggressive, digging wrasse for the sand of a big saltwater tank. It suits a keeper with a little experience.

Did you know

The dragon wrasse's other common name, rockmover, comes from its habit of turning over stones far larger than its own head. It flips them to reach buried worms and crustaceans.

Caring for the dragon wrasse

Give the dragon wrasse at least 106 gal (400 L), with open bottom space and a sand bed at least 5 cm deep. It rearranges the aquascape, shoving rock and coral around as it forages. It also jumps, so fit a tight lid.

Keep the water at 73 to 81°F (23 to 27°C) and a pH of 8.1 to 8.4. Feed meaty foods such as mysis, chopped clam and krill.

The dragon wrasse is aggressive and not reef safe, since it eats shrimp, snails, crabs and small clams. Keep only one per tank. House it only with bold tank mates such as tangs, triggers and larger angels.

Good to know

Novaculichthys taeniourus is the only species in its genus, and it belongs to the wrasse family Labridae. Like most wrasses, it starts life as a female and can change sex to male. Juveniles and adults look so different that they were once thought to be separate species.

In the wild

The dragon wrasse is widespread across the Indo-Pacific, from the Red Sea and East Africa to the tropical eastern Pacific. It lives over open sand, rubble and broken coral near reefs. Juveniles drift near the bottom with a rocking, side to side motion that mimics a loose piece of algae. Adults claim a stretch of reef flat and dig a sand burrow, where they sleep at night.
