I needs some advice here. I got a new copper band butterfly last Tuesday. The first tow days or so I did not see much of him, hid alot in the live rock cave I have built. He now swims around alot, and has been eating. The problem is on his left side fin is a large white spot, almost looks like tissue pealing off. While swimming he does seem to favor this fin by flapping it faster than the other side. I have included a couple of pics. If you know what this is and what I need to do please let me know.
Thanks!!
Thanks!!
