Update: After the removal of the netting, he was pretty much moribound, laying on his side/ upside down and breathing heavily. I gave him darkness and quiet to for a few hours to see if he would turn around. When I checked up on him again he was dead. Thank you everyone for their help and advice, I really appreciate it. I will never use a net again on flasher wrasses.

One of my favorite fish, and I was really looking forward to having him with the other wrasses. I feel horrible but there wasn't much I could do after removing the net, and he was already stressed from shipping, not swimming, just lying on his belly and hiding.
