I have a Foxface with a yellow tang in my FOWLR and they get along fine, hopefully the foxface is already in there and you plan on adding the tang last, if not, you might be in for an adjustment process. After this is over, they should be OK (you never can tell, though, all do not display the same behavioral characteristics)oh, one cool thing about the foxface, he will turn from his bright yellow color to black,white and brown and stick himself to your LR or deco. and freeze when aggrivated or frightened, so if you get one, do not be concerned..It is actually pretty cool..oh, and they have venomous spines so try not to handle them...good luck!
