I’ve had my Katherine’s Fairy Wrasse for three months now and it’s been a joy to watch. The male has a vibrant red stripe that stands out beautifully in the tank. It’s peaceful and doesn’t bother other fish. The coloration is exactly as described, and it’s a great addition to my reef setup.

The fish arrived healthy and looked exactly like the photos. The female is much more subtle, which I appreciate since I prefer a calm, natural look. It’s been adjusting well to the tank conditions and seems active without being aggressive.

This wrasse is a standout in my community tank. The male’s red stripe is stunning, especially under the right lighting. It’s not flashy, but it’s elegant and adds a lot of visual interest without causing any stress to other inhabitants.
