green finger soft in trouble??

hei guys! purchsd her bout a wik ago, and he was completed happy and sudenly this hapen?! all parameters are stable and other corals are stil the sme... no trouble... although i recently added a lil "cured live rock" could this have caused her to be sad??
cheers guys!

 

These corals do not like a tremendous amount of flow so check the flow and maybe move it somewhere else. They are pretty resilient.

 

ok thanks,, ill give it a shot ...how bout on lighting?
