Foxface sting or something else

[scaramanga]

Got home today and noticed my Tomini Tang with White mark on face.

Foxface is a new addition to tank (7 days). Tomini has been very aggressive towards it. Is this a sting from the foxface? The Tomini seems to have backed off and foxface is now swimming the tank freely.

Fish aggression possibly, have you noticed any fighting?

Looks like your foxface gave it a hickey

Looks superficial, perhaps it got spooked and ran into something in the tank? I don't think it needs treatment (because that would require catching the fish out and moving it to a hospital tank). If it gets infected, you may need to do that though. Symptoms of infections would be; increasing size of the lesion, deepening of it, turning red in color, or new lesions forming.
