Do they have an anemone? If so move it they will follow close, then net them

[Douglas]

These fish did not follow their anenome, when it moved one night, to the back of the tank. Their anenome is in a hard place to retrieve, without breaking coral, or dismantling the reef. It's like the fish are lost, or have lost intrest in their anenome. So that might be tough to do.
