The Christmas wrasse (Thalassoma trilobatum) is a super colorful fish that lives in the ocean. It has a few other cool names too, like the ladder wrasse or green-barred wrasse. This fish is a type of ray-finned fish and belongs to the wrasse family, called Labridae.
You can find the Christmas wrasse in the warm waters of the Indian Ocean and the western Pacific Ocean. It loves shallow reefs, usually swimming from the surface down to about 10 meters (33 feet) deep. People sometimes catch these fish for local fishing or to keep in aquariums.

What Does the Christmas Wrasse Look Like?
The Christmas wrasse is a medium-sized fish. It can grow up to 30 centimeters (about 12 inches) long. It has special fins: 8 spines and 13 soft rays in its back fin (dorsal fin), and 3 spines and 11 soft rays in its bottom fin (anal fin). It also has 16 rays in its side fins (pectoral fins).
Colors and Patterns
The colors of the Christmas wrasse change depending on if it's a female or a male.
- Females are usually greenish-grey to light green. They have 5 or 6 dark spots on their back. You might also see some faint dark stripes on their sides. Most of their scales have a thin dark line. They also have a cool pink or dark red mark under their eye, shaped like a diagonal line or a "C."
- Males in their final stage are very bright! Their front half, near the head, is salmon-pink to orange. They have two rows of bright green rectangles on their body. Every fourth pair of these green shapes connects to form a single green bar across their back. Their head is orange-brown with no stripes. Their tail is brownish to greenish, fading to pink at the edges, with blue rays near the end.
This fish looks a bit like the surge wrasse. But you can tell the Christmas wrasse apart because the females have spotted heads, and the males have different head colors.
Where Does the Christmas Wrasse Live?
The Christmas wrasse lives in a huge area! You can find it along the east coast of Africa, from Somalia all the way down to South Africa. It also lives across the entire Indian Ocean. In the Pacific Ocean, its home stretches east to Pitcairn Island. It goes north to the Ryūkyū Islands in Japan and south to northern New South Wales in Australia.
Home and Habits
The Christmas wrasse loves to hang out in places where the ocean waves hit the reef. It lives on reef edges and flat reef areas. These spots usually have a mix of coral, algae, and seagrass. It stays in shallow water, from the surface down to about 10 meters (33 feet).
What Do They Eat?
This fish is a carnivore, which means it eats other small animals. It enjoys a variety of tiny creatures like crabs, molluscs (like snails or clams), and brittle stars. Younger Christmas wrasse mainly eat small invertebrates that live on the ocean floor.
Reproduction and Life Cycle
Christmas wrasse are oviparous, meaning they lay eggs. A male and female fish will pair up to spawn (release their eggs and sperm). After the eggs hatch, the baby fish (larvae) float around in the water for about 60 to 99 days before they settle down on the reef.
How Do People Use Christmas Wrasse?
The Christmas wrasse is sometimes caught for the aquarium trade. However, it grows quite large, so it's not the best fish for most home aquariums. It's only a small part of local fishing for people who fish for their families or small businesses.
