The Multicolour Wrasse is a vibrant addition to my reef tank. After a few months, the fish developed a bold pattern with clear orange and blue accents. It’s active but not aggressive, and it seems to enjoy the rockwork and sandbed. A great choice for experienced marine aquarists.

I bought this wrasse for my 120-liter tank. It’s been two months and the fish has grown noticeably in colour intensity. It’s not the quietest fish, but it’s not aggressive either. I recommend a mature system with proper hiding spots.

The colouration is stunning. The fish changes its pattern over time, and now it’s more vivid than when I first got it. It’s active but stays within the tank, and it doesn’t bother the corals. Very satisfied with the purchase.
