I think my copperband is a masochist

[apercele79]

I've had a copperband butterfly for a couple of years but yesterday I traded in my huge heniochus diphreutes for a baby one. I noticed this morning a part of the copperband's tail is missing but he always swims next to the heniochus, who randomly bites hit tail. Instead of swimming away from it, the CB is the one who goes back to the heniochus, who will randomly take a few bites of his tail

rather unusual behavior, you would think the CB would stay as far from the heniochus as possible

He might be exerting his dominance.

Hopefully this is only a temporary thing since they've been tank mates for less than 24 hrs. If this behavior continues, I may have to get rid of the heniochus
