Copperband #1 Medium size I have had for 10+ years, whether it was my 200 or now my 300 I have never seen Aptaisa in the display, only in my overflows/sump. I tried adding a feather duster and he loved it so it was removed. He has never bothered any other corals
Copperband #2 Medium size I had him in my 158 4+ years never ate aptasia, I made the dreaded mistake of trying to pair up with #1.
Copperband #3 Small size I put him in my 40 to eat Aptasia, never did just ate PE Mysis like a pig and went after my wife's jaw fish which was a not good, so he went back to the LFS
