yellow tang verses copperband butterfly

[Doug]

I have seen situations where the tangs will not leave the copperbands alone. This seems to be the worse with larger copperbands. We had to remove one from a friends tank because of his yellow. Found a small copperband & the same yellow ignored it.

When I added my 2yr. old copperband back to my tank with a kole in it, the same happened. I removed the kole until the copperband was established and then replaced him and they were fine.
