The McCosker’s Flasher Wrasse has become the centerpiece of my 75-gallon tank. The male is stunning with its vibrant red and blue patterns. It’s active and doesn’t seem to stress easily. I’ve had it for six months and it’s thriving in the established environment.

Great color and movement. The male is very eye-catching with its red band and blue stripes. I made sure to use a secure lid since it does jump occasionally. The tank needs to be stable, but once settled, it’s a joy to watch.

I bought this wrasse to add color to my reef tank. It’s been a hit with both my fish and visitors. The female is calm and blends well with the other species. The male is bold and active, especially during feeding times.
