Joseph Ferguson –
Bought this wrasse for my 150-gallon reef tank. It’s active and peaceful, doesn’t eat corals or invertebrates. After a few months, it’s grown to about 4.5 inches. Very satisfied with the coloration and behavior.

The fish arrived healthy and has been thriving in my tank. It’s a bit shy at first but becomes more confident over time. I appreciate the detailed care notes included with the purchase.

Perfect addition to a mature reef setup. It’s visually striking with its bicolor pattern. No aggression observed, and it coexists well with other reef fish.
