Glad to see that the tank is doing so well! It's kinda funny how many of the same things that have happened to you have also happened to my tank as well. I had a monti that bleached because it was being nipped by a Sailfin and a Coral Beauty, so I got rid of those and after 4 months of nothing it's now back and growing everywhere! I too had a Copperband but it only lasted about a week. Made me sad, was a great looking fish. What is you Wrasse list in the tank now? I lost my Tonazu, But I now have a Clown Fairy, and Blue Fairy Flasher, a Yellow Coris, Mystery, Christmas Wrasse and another type of Blue Fairy. Love them! Most active fish in the tank and are doing so well! We haven't seen an update in a while, but I hope all is still well with you and your tank.
