We kept an Orange Back, Exquisite and a Clown (Solarensis) in a 230. The Orange Back was the most aggressive of the bunch and rivaled the Purple Tang. He also has grown to 5+" and is a beautiful fish.They didn't have the exquisite wrasse so I let them substitute. I got the orange back.
He has been relocated to the 180 FOWLR and is learning to get along with the 2 puffers and Picasso Trigger in there now.
