Pretty discouraged :/

Full tank shot?
Like to see the powerhead placement & lighting relative to coral placement.
Thats what really affect them most.

+1 on checking for buggies, They're not all that common, but I've had little white bugs wipe out some euphyllia.

All you # are in check, can't find any hiccup in that.
Maybe a Triton test will give you more info especially on the metal parts in a tank.
Euphyllia are super sensitive for copper, even just a little.
It happens to me once awhile too, yes i.m a Acro dude but between the 100lb of sticks I have somewhere also about 2lb of these awesome Euphyllia's and some how sometimes I just lose a head or two for no reason.
Keep telling myself that it must be happening in nature too.
Maybe a few heads of the regular green Euphyllia from a local reefer as that been aquacultered and will act stronger in your tank.
Keep us informed.

Ever seen those peppermint shrimp on your corals? specifically any of the corals that started receding and died? - just curious

Nope, just when they're trying to steal food.

Had to ask I'm on the Pest train here. I'd like to hear the results of a dip on these corals.

Is Lugol's still the preferred iodine dip?

 

[christ1991]

Look for flatworms. Also when you do decide to pull the skeleton, I would look for a burrowing pest. I have seen some kind of white muscle,or filter feeder that burrow near the mouth of the euphyllia.

 

[AllSignsPointToFish]

Are euphyllia sensitive to elevated magnesium levels?

 

[christ1991]

I have used lugols or betadine

 

[AllSignsPointToFish]

Never used betadine. What is the procedure for using betadine?

I have had my MAG over 1500 while tuning my auto dose without issue

I've had my frogspawn for over three years and it has been one of my hardiest corals; has gone from a 1 head frag to over 30 heads. I added some peppermint shrimp a while back and one of them immediately went to town on the 'spawn, it took me quite a while to get the little buggers out but in hearing your woes I would keep a very careful eye on those shrimp.

Okay, cool. I was just curious.

Interesting. Did they bother any other corals or just the frogspawn?

I've had that with a wall hammer & that burrowing feeder took it out,
but;
if OP is having multiple issues with these corals, I also suggest a Triton test as suggested to get a better diagnosis of water chemistry.

Tank looks good.

I dip euphyllia in bayer, iodine, RX etc.. With great results.

Just the frogspawn and it was immediate but I got them out of there before they had a chance to hit the buffet.

You dip euphyllia in all of those before introduction or you've just used all of those on euphyllia?

I hand-feed all of the peppermints, so they're not really hungry as far as I can tell. Actually, they're quite fat, which might explain the phosphates. lol

 

[steve&mari]

I've also used Bayer,rx,iodine all great to use

 

[chefjpaul]

Have and do use as needed / prior to introduction.

I prefer bayer, but can't always get in NYC.

Not all at once....lol.
That's a cocktail for destruction.
