I am trying to switch from a semi predator tank to a peaceful, fully reef safe tank. I started by getting rid of my main aggressor which was a Picasso trigger. Next I had to get rid of my pair of Bird Wrasses. Now, my Kole Tang has an attitude.......if I keep removing fish I won't have anything left. I can't seem to add anything without one of my existing fish becoming a bully? I am afraid if I remove the Kole Tang, my Pajama Cardinal will become a terror lol
