Bought this wrasse for a 75-gallon reef tank. It’s active and colorful, though it does chase smaller fish. Needs a well-established tank with plenty of hiding spots. Adjusted the fish placement to reduce stress on others. Overall, a striking addition to the tank.

The fish arrived healthy and looks vibrant. It’s aggressive, so I made sure to keep it in a larger tank with strong, dominant fish. Not for a small or beginner setup. Still, it adds a lot of visual interest.

Great color and movement. After a few weeks, it started cleaning the tank by picking up debris. I’ve had to monitor its interactions closely, but it’s a unique and lively presence in the reef.
