Summerdaze you will spend tons of money in this hobby killing corals if you don't stop and take the advice of people on this site.
Just a couple days ago you were asking about how to get copper out of your tank.
Now you are adding corals and wondering why they are dying.
I am not sure if you have upgraded your lighting yet, but if not the lack of light and the copper is probably what killed your xenia.
Can you tell me what light you are currently running and what steps you are taking to remove the copper from your tank?
How old is the tank?
What are your water perameters?
You need to learn patience.
Don't rush or you will only kill more corals, and probably some fish too.
fish will tolerate poor conditions, but most corals won't.
Please understand that I am only trying to help, but you need to listen and understand what I and many others have said to you.
Please respond and answer the above questions.
anyways should I leave it in the tank , it was only a small frag and Im wondering if It will come back, let me know , thanks
