I have recently had some issues with my Euphyllia. I had 8 in total - 6 hammer / frogspawn type, and 2 torches. My tank is a year old and over the past 3 months things have really taken off, including these Euphyllia. Growth has been very pronounced with them all showing great extension and all showing growth, with some showing a lot of growth (one torch has more than doubled). The whole rest of the tank is similarly thriving.
However, about a month ago, I suddenly had 2 of my frogspawn / hammer variants start to show much less extension, and over the course of about two weeks day by day they showed less and less until they were literally disintegrating off their skeleton (pieces falling off). All the while the other 6 (which are all in close proximity) looked as robust as ever.
I chalked it up to bad luck and nearly a month has gone by without incident and the remaining 6 were looking look great. That is until about 3-4 days ago, when the same thing started with one of my 2 torches. I've had this for almost a year, and it was looking amazing just 1-2 weeks ago. Over the course of the last week, it has extended less and less and now it's starting to show some skeleton and I assume it's on the same trajectory.
I did examine my first two skeletons when I removed them from the tank and didn't notice anything funny and they didn't have any signs of brown jelly disease - either visually or by smell. Anything else I should be inspecting when I likely have to remove this one?
What else could be going on? I don't want to sit in fear of randomly losing one after another, especially as these have been growing so well. This torch is right next to my other torch that has nearly tripled in size and is looking great (see photos). They used to be similar size!
They are not touching any other corals.
Tank parameters have been really stable and consistent for months.
pH 8.1 - 8.3
Kh 8.0 +/- 0.2
Ca 450
Mg 1300
NO3 4-6ppm
PO4 0.03 - 0.07 ppm
Temp 78
Here is a bad picture of it a couple weeks ago, showing it's size and extension:
Here it is today:
Here is a pic of one of the 2 I lost a month ago:
Another pic from a month ago where you can see the 2 that died, as well as the current one looking good:
