I bought this wrasse for my 75-gallon reef tank. It’s active and colorful, though it does show aggression toward smaller fish. I’ve had to remove a few small shrimp to avoid conflicts. Overall, it fits well in the tank and adds visual interest.

Great addition to my aquarium. The fish is vibrant and stays active. I made sure to keep it in a spacious tank with plenty of hiding spots. It’s not the most gentle fish, but it’s worth it for the color and movement.

The wrasse arrived healthy and seems to be adjusting well. I’m cautious about its behavior around other fish. I’ve observed it chasing small invertebrates, so I’ve limited tank diversity to avoid stress.
