So I have an acro that's STNing*, and it seems to me that dying tissue might fluoresce bright green, while normally the color is kind of reddish (especially for new growth) or in older tissue a less bright green.
Is something like this common? I mean, is it common for dying tissue to become one distinctly different and/or bright color right before death?
Here's a picture showing what I'm talking about. Note the tissue near the dead parts is clearly green. Has anyone else see dying tissue take on extremely bright colors like this prior to death?
* Not terribly interested in doing anoher "help my coral is STNing" thread, but in the odd chance someone is interested I'll get this off my chest.
Background: @madweazl very generiously gave me a dream coral colony. Looking around, I tentatively identified it as Acropora plana (http://www.coralsoftheworld.org/species_factsheets/species_factsheet_summary/acropora-plana/) and some sleuthing around the internet seems to show it available in from @Battlecorals as "Shag Priority" (https://battlecorals.com/products/shag-priority). (so my name for it is @madweazl 's Shag Priority)
It used to have very modest tissue die off as other new growth blocked out the light, which is normal I think for branching corals. But the tissue death seems to be more and more prevalent on tissue that previously would be fine. Before, mesenterial filaments were out all the time and very active, now I rarely see them even on the healthy issue and PE is not so hot. The green "dying"issue has polyps which even extend modestly.
The culprit may have been an accidental 1.4 dkh jump almost exactly a month ago now. It may also not like the new alk additive, Tropic Marin All-forReef vs. the previous ATI essentials added three months ago, but I'm not sure. Or it might have been the flucanzole treatment I did two weeks ago; the STN accelerated after the flucanzole, while it was very sparse before - though correlations != causation.
Other corals are doing fine, some even growing decently, during the flucanzole treatment. I already have four frags of this MW shag priority which are dong fair-to-middling (which I got from not being carefuly when I put my hands in the tank! The first such frag grew awesome for the first two months and has been static ever since, but is otherwise doing OK), and I think I will make a few more in the hopes that some of them will survive the apparently imminent death of the main colony.
