What's Killing My Anthelia?!?!

[howardj]

I cannot figure out what is it. Everything else in the tank is Perfect, even xenia (same family) so I have no clue. I turned the lights on real quick last night after they had been out for awhile, and I found a small brittle star on the the anthelia (2"dia.) Could the star be eating the polyps?

ive never had good luck keeping both xenia and anthelia, same with some others

Hmmmm, i don't know, but let me know when you find out, so i can get rid of mine! Man, this stuff spreads MUCH faster than my Xenia does. At least i can trade my xenia back to LFS for credit.
