Black spots and tissue loss on Kenya Tree
 

Hello,

I had a kenya tree and a finger leather in my QT tank for about a month and suddenly they started looking pretty bad.
The kenya tree started fragging itself with 3 healthy pieces breaking off. The rest kind of shrunk and then became brittle and just fell apart.
The finger leather had a black spot which sluffed off easily when I scraped it with my finger, revealing a hole in the base of the coral. The polyps actually opened up on it the next day, but it appears to be releasing the rock it's attached to.

Anybody no what's up?

Nope..

What is your water quality? What lights are you using? Are you feeding it at all?

These are in an EVO 13.5 with the stock lights. I have not been feeding the corals, but have a pistol shrimp and watchman goby which I feed very little. The parameters are all good. I did use a little pukani rock that I didn't cure and have had to deal with a lot of cyano and diatoms, but my devils hand, toadstool, mushrooms, and candy canes are all doing great. I had some zenia which were on the same rock as the kenya tree which died first. Maybe a week or two before I noticed the kenya tree going down hill.
