I am not sure if I would do this, I have been looking into keeping one of these (Sixline/goldstripe) Soapfish for just over a year now and researching.
They will eat anything that can fit into their mouths including Groupers. This fish can discharge a toxin when stressed, they can poison tankmates.
This is where I question keeping one myself, if you do run Carbon 24/7, keep a stress free environment and feed well. Just be prepared for that just in-case situation you may run into.
This is one fish you may really want to do your homework on first.
