Grace Slater –
Bought this wrasse for a 75-gallon reef tank. It’s active and colorful, but it does show aggression toward smaller fish. Needs a strong tank setup and careful monitoring. Works well in a well-established system with larger, calm fish.
Wendy Payne –
The fish arrived healthy and looks vibrant. I noticed it’s quite territorial, especially during feeding. I’ve had to keep it away from smaller invertebrates. Still, it adds visual interest to the tank.
Anna Lambert –
Great addition to a larger reef tank. It’s active and maintains a good color. Only issue is it attacks a few of the smaller shrimp. I’ve since moved them to a separate tank. Overall, a bold and striking fish.
