Jake MacLeod –
This wrasse has been in my 150-gallon reef tank for six months. It’s active and helps control algae, though it does occasionally nip at smaller fish. I’ve added some larger, more robust species to minimize conflict. Overall, a good addition with proper tank setup.
Carol Wright –
The fish arrived healthy and has been active since setup. I noticed it’s semi-aggressive and avoids direct contact with my clownfish, but I keep a close eye on tank dynamics. Works well in a spacious reef environment.
John King –
It’s not the most peaceful fish, and I had to adjust my tank layout to reduce stress. Still, it’s a valuable species for algae control and adds visual interest to the tank.
