Mouth on clownfish turning white

[DIZZLE808]

As I was adjusting the PH's in my tank I noticed my clown had some white around his mouth...any insight as to what it may be. He's been in the tank for about 2 weeks.
55 gallon

Ph- 8.0
Ammonia-0
Trites-0
Trates-less than 20
Salinity- 1.024

Is it just a loss of color or is the white mark a small raised lump on the fish?

Doesn't appear to be swollen or anything

My best guess would be an injury of some kind . If so it should go away pretty quick . Keep an eye on it and if it gets any worse post some more pictures .

Will do. As soon as the lights turn on I'll be able to get a good look at him
