I got my copperband from an LFS
that trains them onto prepared and takes really really good care of theirs. They dont' even sell them until they are eating frozen so I had a head start with mine. The lfs
had him eating by hand even which posed a problem when I first introduced him tot he tank. lol It did take mine a few days to settle in though so be prepared. He was very shy and not very aggressive when it was feeding time in the beginning but after about a week or so he got into the groove.
I still feed mine out of a turkey baster, he seems to really love pulling the shrimp out of it and it gives me the chance to make sure he is eating.
Good luck Kio, take care of him and watch him closely in the beginning and you should be good.
