I'd harpoon the 6 line and get a small school of Lyretail Anthias. 6 lines will most likely turn on any other wrasse or anthias, or anything remotely similar to them at some point. It usually takes a couple of years, but most of them do ime. The last one I had cost me 3 Bartletts Anthias, a 5 Bar Mystery Wrasse, and a few Flasher Wrasse among others. I think you were here when he was banished to the mantis tank I had set up at the time. Sorry to say, but the clowns may be a problem with any other fish you add also. I had a pair of Tomatoes that took over one side of my 210 a few years back. They would chase every fish, no matter how big, to the other side of the tank. I had to remove them to their own yank. The female draws blood pretty much every time I put my hand in that tank. I would expect a pair of maroons to do behave the same to any new fish in your 72.
