Well, you all know by now (if you've been reading thus far, anyway) that some of my corals are headed down the tubes. I blamed too-high phosphate.
What piques my interest is that the rest aren't following suit.
The acan wouldn't puff or eat and the goniopora had no PE and was beginning to bleach. The leptastrea, however, has perfect PE and still chows down as voraciously as ever. The mushroom - not surprisingly, being a softie - is doing fine, even despite repeated dumps off the rock and into the sand....and the diploastrea I bought browned is starting to get its color back and sends out a couple tentacles at night. Not a full recovery yet, mind you (and I haven't figured out how to feed the durned thing, either), but definite improvement.
SO.
Recalling an article I'd read about corals in the shade faring better during mass reef bleaching events, and having realized that I drastically changed the photoperiod when I changed tanks (not to mention the LED light's spreading differently), I shoved the unwell corals into shaded areas a couple days ago. The goni appears to have stopped bleaching and even shown a tiny bit of PE, though my acan has not yet shown visible improvement. At least, it doesn't seem to be getting worse.
We'll see what happens.
