Need Your Thoughts Please!

So these are considered the easiest or beginner corals but they seem to be my arch nemesis at times. I love them but they seem to usually be finicky, close up, or just dry out with time.

I make sure detritus doesn't rest on them, they get decent flow, but sometimes they seem to just go into this weird funk. I grow Acropora, Frogs, Torchs, etc. with no issues at all. This is my only weird problematic coral.

Any Ideas? I dosed them in ReVive for 10 minutes and noticed a little worm on one of them. Can it be the small star fish or something irritating them?

Some zoos are more finicky than others. But if you've tried a few different varieties and none of them made it, that's weird. Don't give up on the frags plugs though, cause I had a zoo colony of Purple Nurples die and then mysteriously come back. The more high end zoos seem to be more sensitive too. Maybe try a hardier variety?

Could be little stars at times(but that shouldn't be a problem with that) check lighting, some are a lot more picky than others, what types are you trying to keep?

Make sure you do a good maintenance schedule, keeping stable parameters.
Your light needs to be for reef systems. If you're keeping Acros and so I would think/hope you should be fine with the zoas. I would avoid LEDs and go towards T5s and/or MHs for reefs. It's just too much to take the risk of *hit & miss* that many people talk about LEDs today. Not worthy to me and it's too much money just for a trial.
That's the main reason I suggest HOT5s. It's uniform distribution and availability of spectrum combinations allows the best nowadays for zoas IMO. Do you want to offer them the best? Or do you prefer to "save the electricity"? With T5s and/or MHs you have no *hit & miss*! Waste of time/money when you consider long term reef health. Just my $.02 on that subject.

Considering the light is indeed good, parameters are stable, with proper maintenance schedule, the problem should be related to water chemistry, flow or quality of livestock, when there is no predators or irritators in the system. That is true if you've got a healthy specimen.
Make sure you properly dip all new additions before introducing them in your display.

You could drop a little your alk (9-10) and Ca (380-420).
Please make sure your "salinity" is around 1.023 - 1.024.

Good luck!
