Red Coris Wrasse

The Red Coris Wrasse is a striking marine fish known for its dramatic transformation from juvenile to adult. As a juvenile, it wears a vivid red body dotted with black-rimmed white spots, but as it matures, its coloring shifts to blue with fine speckles and a bright yellow tail, a change so complete it can look like an entirely different fish. This large wrasse can reach up to 40cm and has a natural habit of burrowing into sand, so a spacious tank with a thick layer of fine sand is essential.

About Red Coris Wrasse

A large wrasse whose appearance changes dramatically from juvenile to adult, growing up to 40cm. It burrows in sand, so a spacious tank with a thick layer of fine sand is needed. Considered suitable for intermediate keepers.

7 things to know before welcoming a Red Coris Wrasse

1Juvenile and Adult Look Totally Different
As juveniles, Red Coris Wrasse have a red body with black-rimmed white spots, but as they mature the coloring shifts to blue with fine speckles and a bright yellow tail. The change is dramatic enough that it can be hard to believe it's the same fish, so consider both the current size and future appearance before bringing one home.
2Adults Can Reach Up to 40cm
Most individuals settle around 20cm, but under good conditions this large wrasse can grow up to 40cm. It's worth preparing a tank that will stay spacious enough as the fish matures.
3Natural Sand-Burrowing Habit
Red Coris Wrasse like to burrow into sand to rest or hide. Providing a thick layer of fine-grained sand lets them express this natural behavior and helps reduce stress.
4Needs a Spacious, Wide-Bottomed Tank
A tank with generous floor space and depth gives room for both burrowing and swimming. Choose fine, rounded sand such as coral sand and lay it down thickly.
5Active and Constantly Swimming
This wrasse is curious and always on the move, giving it a strong presence in the tank. That said, it will dive into the sand and hide if startled.
6Intermediate Difficulty Level
Red Coris Wrasse are considered suitable for intermediate keepers. They suit anyone who can prepare the right tank size and substrate in advance.
7Prepare the Setup Before Bringing One Home
Given its adult size and sand-burrowing habit, it's best to have the tank, substrate, and water quality management ready before your fish arrives. Without a proper setup, the fish may lack a place to hide and become stressed.
