Xenia is nice but can be a pest coral, the key is to keep it off the main section of LR
in the tank. Growing on the glass is a good thing and easy to get ride of. You got to love it when your tank starts to make you money...
I have a kenya tree forest that I cut down a few months ago and traded it in for some NICE$$$ at the LFS
... Bought my new Sen 900 pump and some other goodies with them..
Shroons are easy to cut off LR
but zoos if they take over a piece of LR
the best thing is to trade for a new coral or get store credit.
