Trachy Question

[C4Rez]

I’m fairly new to Trachy corals. Bought the first one 4 months ago for my WB 145.5. Was doing great (low flow, low-mod lighting under shaded rock at 90-130PAR). Even bought 2 more Trachys last month. Then things got weird this week.


First Trachy. Started off similarly like those shown below (closed).


Got the 2 additional ones (Red & Yellow).

Things get confusing afterwards. The Yellow one eventually dies which was to my surprise because it was doing better then the Red one. Now the Red one appears to be thriving (inflated and great feeding response). And my First Trachy for some reason is deflated and shriveled (last I saw it like this was over 3 months ago).

This picture above was taken this morning before lights on.

HANNA results:
Salinity 1.026
pH 8.0
8.3 dKH
Nitrate 27 (consistently 20-25 for half a year)
Phos 0.06 (consistently < 0.1)
Cal 469
Mag 1405

Any ideas?

Never mind. That was quick. It bailed this afternoon. Tried to save it last night with a KFC dip, but I guess it was too late.
