Added a male and three females to my 60-gallon reef tank. The fish are active and colorful, and they haven’t damaged any corals. The jumping behavior is noticeable, but the canopy keeps them safe. Great addition to the tank.
Alexander Rutherford –
The wrasse looks stunning with its bright red and orange coloration. It’s peaceful and doesn’t bother the anemones. I did have to install a canopy, but it’s worth it for the activity and beauty.
Fiona Ross –
Perfect for a reef tank. The fish are lively and don’t eat any of the corals. I introduced the male and females together, and they settled in well. Very happy with the purchase.
