What is happening to my Kenya Tree?
 

It looks like my Kenya Tree has a brown slime on it. It also hasn't been opening the last 2 days. I do have a frogspawn that is dying in the tank could that be affecting my coral? Everything else in the tank seems fine. Do you think I should remove the Kenya tree or frogspawn before it starts affecting the rest of my tank?

They do that sometimes for no apparent reason. Don'r panic, it will likely get over whatever it's issue is. Mine has gone through those moods once in a whille too and has always come around again just fine.

Yeah the last few days it has been shedding too.

Kenya trees sometimes do funny things but for the most part they are a fairly hardy coral.
That being said, you mention that you also have a frogspawn that appears to be dying so IMO you should take some water tests and post them to see if you have a water quality issue.
The things you should check are:
Nitrates
PH
Calcium
Magnesium
Alk/dkh
If you could post the actual #'s you get from these tests it might help to identify if you have a water quality problem.
If you don't have these test kits or cannot borrow them from a friend then maybe take a sample of water to your LFS and have them test if for you.

I agree with Ruth - Frogspawns (and other softies like that) will go yucky if you even TOUCH them (trust me, I just had to do some adjusting of mine in my main tank and it wasn't happy, shrivled like a big softball sized fist!)

Anyway - water changes, removal of problematic corals and such should help - the fact that your Xenia is doing so well is a sign that your tank isn't doing too too bad!

My readings are as follows:
Nitrite 0
Nitrate 0
PH 8.2
Ammonia 0
Those are the only tests I have
