How long have you had the Yellow Tang?
I've had the yellow for about 6 weeks. Currently I have 2 Ocellaris, 2 Chromis, and the Tangs.
I've given them a big leaf of Nori, and have fed flake twice today, it does seem like the hostilities are dying down, but every once and a while the Yellow comes over to assert his dominance. I was considering adding a Yellow Eye Tang, to make it a non even number since I've heard that even numbers will often lead to more disputes, but I think I'll give it a couple of more days. I am surprised that the blue hasn't hid somewhere waiting for the tide to pass.
