the Copperband Butterfly is the reason I got into saltwater aquariums to begin with. After learning about Copperbands' poor survival rate I refuse to take one from the ocean. Without experimentation no one will ever find out the "key", but I prefer to leave that to experts. Good luck with your farming. I haven't ever found Aiptasia to reproduce at a fast enough speed to farm them.

You might get lucky and the odd reefer will post that he has had success for a few months probably after several deaths.
The rest try once or twice and the fish predictably dies.

Best left in the ocean as a few others have suggested.

0 for 2 on the copperband, still think its an ocean fish along with morrish idol and achilies tangs

My first cb- and I have had him just over two years and still going strong.
The only thing he eats is mysis and pacifica plankton and anything he can get from the live rock.
