Platy Health Question

I got a new male on Thrsday (sunburst) He's been fine the tank so far, but tonight I saw a little discoloration just behind his head. He's not acting unsual. And it does not look like ich. The best way I can describe it is like a film, grayish is color. It looks as if I could just wipe it off. Sound like anything I should worry about? I can't get a good enough picture to show him off, sorry. My biggest concern is that I have 3 pregnant females in there and don't want the mothers or fry compromised. Thanks for any help!
