Hi all.. My peacocks have been doing fine but lately my biggest peacock has been scratching itself near its fins/head on the left side a lot. I see it try to rub itself against on the rocks (gravel) around the same area and even on the windows of the tank along with other objects. It doesn't have this behavior all the time but I've seen it atleast 2-3 times (After i feed him) and now I'm concerned something is wrong. I've checked him for Ich but see no such things. Could be something else but I am stumped on what to do. My LFS don't really know much. Anyone have any idea on what I should do? I really like him as he is just beginning to color up and become so nice.
