Did you know
The adorned wrasse can vanish into the sand in an instant when startled. It stays buried until it feels safe again.
Caring for the adorned wrasse
Give an adorned wrasse at least 50 gal (190 L) and a secure lid. A soft, fine sand bed a few centimeters deep is essential.
Keep the water at 73 to 81°F (23 to 27°C) with a pH of 8.1 to 8.4. Feed mysis, enriched brine shrimp and other meaty foods.
The adorned wrasse is peaceful, active and safe with community fish. It leaves corals alone and helps control pest bristleworms and small snails. It is only reef safe with caution, though, since it may eat ornamental shrimp, small snails and fan worms.

In the wild
The adorned wrasse ranges across the Indian Ocean, from the East African coast and the Maldives south to KwaZulu-Natal. It works over rubble and sand at the base of reefs, picking small invertebrates from the substrate.
