I noticed today that my smaller clown fish has some growths on it. It seems to be only on the white stripe closest to its face. There are no growths on the bigger clown. Any ideas what it may be? Here are some photos.

Is the clown a new addition or has it been in the tank for some time? What are your water parameters (PH,ammonia, nitrite, nitrate)?

Also, did the clown dart for the anemone or did it slowly acclimate to it? Nuzzling, biting, swimming beneath it etc? Almost looks like nematocysts.
Has the clown ever been QT'd/treated for anything?
What other fish are in the tank?
Has it shown interest in any corals? Specifically Euphyllias

Both clowns are the first fish I had sometime in oct.
Ph is abit low 7.9 (working on it)
ammonia 0
nitrite 0
nitrate 0
they both were slow to acclimate to it.
no its never been treated for anything
I have 4 blue striped gobys
and a little green striped goby
In my tank I have zenia, zoas, feather dusters, a clam, a couple shrooms and green star polyps

The pH is very concerning. What is the reading later in the day and what time was the 7.9 tested? Is the tank top covered and do you have a sump?
I would pro actively do a few good water changes with well aged/aerated SW. It will help with any possible bacterial/viral problem and well as improving that pH. Low pH is not going to cause what your seeing but it's not going to help it either.
Watch the clowns behavior to see if it keeps leaving the anemone for long periods and tries to return to the anemone.
What was the last wet item added to the tank, how long ago?

The ph stays stable its just low Im adding buffer at this point but just started that yesterday.
I added a blue stripped goby two weeks ago
I will do a 10g water change tonight
and yes I have a sump about 12g
tank is 30g

Take your pH kit to the LFS (not your water) and have them test it against their test kit. See if they both come up with the same reading. I'm guessing they won't.
You did not say whether the tank was covered or not but poor ventilation into the tank and/or poor water flow throughout the tank are going to be your largest contributors of low pH. CO2 becomes trapped in the system and suppresses the pH. Adding buffers is a poor solution and generally short term fix that does not work. Unless your alkalinity is low, do not use a chemical additive to fix an environmental cause. Allowing the tank to breathe better will usually fix the problem. Sometimes it's as simple as opening a window.
What species is a blue stripe goby, that seems like a few fish for a 30 gal system.

My tank is covered and I need to add some ventalation for sure. Its a new cover and the tank gets to warm by the end of the day. I may not have enough water flow in the tank and that has been a concern of mine. All I have is a rio 3300 for a return pump. As for the blue gobys they are the neon blue gobys (Elacatinus oceanops) and they are pretty small

If the tank is heating up as the day goes on, ventilation should be top concern. Fix that and you fix the pH problem. Is this a custom lid or simply a plastic/plexi fitted lid?

If it's a custom hood, make sure there are plenty of vent slots and a fan pulling air out, not pushing air in. Especially with fluorescent lights, large cumbersome fans are not normally necessary. Usually one good 4" fan at one end (hood size dependent) and a "vent slots" at one end or the sides is enough. On a 30 though, it should be more than ample.

How is the clown BTW?
