Best of luck with the new catch!
I saw during a recent video by a reefer in Singapore, Koji Wada needling a liopropoma after being in the tank for a while. He has a certain way he does it and has done it on other specimens that went on to be fully healed.
These were collected on nitrox. I do sometimes dive with ccr, when I first started collecting I would use ccr, gives you more of a stealthy approach but now its not necessary. Why you ask?
cool, I'm all about safety...and baby angels, lol, or rare, oddball, hybrid angels/triggers you may come across wearing that rig or your ccr rig....:beer:
