Gavin Hemmings –
Bought this wrasse for my 100-gallon reef tank. It’s active and helps with cleaning algae. I had to be cautious with tankmates due to its aggressive nature. Overall, a good addition to a mature reef setup.
Jason Terry –
The fish arrived healthy and has been thriving in my 75-gallon tank. It’s more active than expected and does eat a variety of foods. I’ve had to remove a small shrimp that it chased, but otherwise it’s fine.
Sophie Alsop –
It’s aggressive and not suitable for a small tank. I kept it with a few larger fish, and it showed signs of stress when new. After a few weeks, it settled down and started cleaning the tank.
