Please Help!! What is this on my clownfish??

[Santa26]

So I recently bought my clownfish from my lfs and it seemed fine. I had him in a bowl with my rose bubble anemone to try to get to host it and now that I stared noticing what is this that it has on its face and it is contagious. I have another clownfish and coral beauty ( both of those are healthy) please reply asap!!

Hard to tell from the pics, but looks like it could be uronema or brook. I would treat all fish with a formalin bath. It also could be aggression from the other clown.
