compatibility issue,,Chevron nipping at flame angel

[BioMan]

I put a flame angel my friend was holding into a (265 gal) tank that had a Chevron tang in it and the tang is going after the angel. My friends that aren't on this forum that have been in this hobby a while never heard of these fish fighting....any ideas?

I have a flame angel and a chevron tang in my 180 and they just get along, but the flame was in there first. When I broke down my other tank I added my coral beauty in the chevron went after him relentlessly, until the flame noticed what was going on and he kind of defended the coral beauty by going after the tang. For now the flame is the peacekeeper and he keeps the chevron in check.
