Whats up with my Montipora Cherry Tree

[Gsponi]

Hi Guys
I have a Montipora Cherry Tree in my Tank and since 3 days it started to disintegrate.

I put here in the Tank 2 Weeks ago .
The Coral was already 10cm long and mostly flat. I put her aside of a Rock , in the Hope She will grow up the Rock.
A few days ago i saw, that she is starting to deform, like make a belly.
2 Days ago i saw a little white spot and i did Dip here because there where some little little Worms in an old Snailhouse she was groing on.
Totay i Saw that she has mssive White Spots and started to disintegrade.
I dont think it was because of the Worms.
Is it possible , that she makes the big belly to grow tonthe Rock and because of that some Spot didnt get enough light?
First Photo is the Original Spot where i put here first second is the spot shes hit the Rock and third is on the Right side.

PO4 0.02
NO3 3.0
CA 435
MG 1200
KH 8
Temp 25
Salinity 1023

the Datas where stable .

Its in the corner which is the lowest flow lowest light area. It likes high light and strong flow.

There is not that bad if a flow because of my Pump in the other corner but yeah i thoght that the light could be the problem.

Whats a good Coral for low light Bare Bottom?
Thx

mushrooms, acans, blastomusa, zoa's, candy canes will all do well in low light. There are many more but this is just what I can think of right now. Good luck
