HELP!! Fox coral losing tissue!!

[One_Divided]

I'll share my expereince with fox corals:

I believe fox corals to be the most sensitive LPS.. Although I have never kept an eligance. Mine (now owned by steve) would be the first things to close if anything was every wrong with my water quality. I found it did best with low current/low light. I am pretty sure I have read that they don't ship well.. and it makes sence looking at their skelital structure.. From your pic it looks to me like it may have been damaged before you got it.. On the other hand, any nitrates in the water will **** it right off.. Sorry I can't read over the entire post!
