Pocillopora thrived, now rapidly dieing?

[SaltieG]

I can't quite seem to figure out what has killed my green pocillopora. I got it as a small frag and over the last year it has grown to atleast 10x that size. Within the last week it has lost most of its polyps and gone white. Nothing in the tank has changed and I cannot figure out what happened. My last resort was to frag off some of the remaining live parts and hope they survive. The only thing that I can possibly think of was I had some pulsing xenia growing close to it so I decided to remove them and they released alot of their "gunk" (for lack of a better term) around it, and that may have possibly irritated the coral enough to send it downward? I did that a few weeks ago and within the last week this thing has went far south. Any ideas or anyone else experience this?

I've chopped down Zenia with no I'll effects. On the other hand if the Zenia slime settled all over your Pocillopora and hung there then that migh have been a big problem. How much Zenia did you remove? Water change?

It was a fair amount that I removed and there did seem to be a lot of slime from it, though I didn't notice any settle on the pocci. I believe it was the next day that I ended up doing a water change too.

Might be a little late but good to run some fresh GAC after a major soft coral pruning. Sorry about the loss. :uhoh2:

Mine has done this before and eventually came back. I would take a small frag and leave the colony in the tank to see what happens..

I will leave the colony in the tank as there are still some small spots left that I can only hope come back. I did take some frags, however by the next morning they were completely without polyps.
