It is a difficult question to answer because every fish is different as is every display. Onus is on the hobbyist to make that decision on what is an acceptable risk that they are willing to take. If it is accepted then what mitigation plan is in place for safe (both fish and hobbyist) removal. Things to consider is reef size, established or not, fish in display, size of fish to be removed, etc. All stressors to both animals and aquarist...go figure.
There are captive bred now from Biota that may be worth considering. Start small, young, feed heavy a variety of foods, may be a safer play. Wild, well, survival of the fittest so probably not going to change it much. Ease of food availability or not.
I introduced both a pyramid and zosters butterfly. I figured some of my soft corals are at risk. I moved some small frags I created to the refugium for a back up plan. Probably was wise, or I was lucky, because they both went to town on Xenia. Cleared out the entire display within 20 days. And I had a lot. I figured it was worth the risk and I had a backup plan to move it elsewhere or reintroduce at a later time.
If you really want to give it a go I'd recommend captive bred. Feed often. I mean often (I personally feed every hour pellet via a auto feeder). Feed quality frozen at night such as LRS reef, coral, and nano. Mysis, brine, etc. Full belly may help. Just saying.
Beautiful fish. Be prepared. Have a backup plan. All the best.
