Edward Greene –
I added a Hardwicke Wrasse to my 75-gallon reef tank after researching compatibility. It’s active and helps clean the sand bed. I’ve noticed it’s quite aggressive toward smaller fish, so I removed a few shrimp. Still, it’s a good addition for a larger tank with strong fish.
Anthony Sutherland –
The wrasse arrived healthy and has been active since setup. It’s not shy and spends time near the rockwork. I’ve had to monitor it closely, especially with smaller invertebrates. Works well in a spacious tank.
Joanne Roberts –
It’s aggressive and not suited for a mixed community. I kept it with only larger fish and no corals. It’s active and helps with algae control, but requires careful tank planning.
