More observations

[Aquattro]

So, due to all the muckin' around in my tank, it's no surprise tht the corals are a bit stressed. I recently lost a largish table. I had some tissue loss on it, so I cut the whole thing up into frags and placed them in various locations in the tank. They were all fine for a few days, but them as if on queue, they all RTN'ed at the same time, regardless of location.
I'm just watching my last frag of blue milli do the same thing. I had 3 frags of it, and all within a 24hr period have sloughed tissue. The last piece will be gone by the end of the day, I'm sure.

It appears that when it's time, it's time. Certain things appear to trigger death or RTN to all pieces of a colony, regardless of being attached to the same colony or in frags. Pieces beside these are doing fine.

I also noticed this when my chiller blew a fuse while I was away. All my frags and the mother colony of one species only were completely dead upon my return.

Just food for thought....
