I personally am no master reefkeeper, I have had good luck with the green ones. But yes they are a hard species to keep in any fashion. I only know from my own exp that they tend to do best for me when I absolutley leave them alone. Place them in nice light and gentle flow and resist the urge to touch move or play with them.If i do move them , I make myself wait at least a week before doing so again. They have such a drastic change from open to close so its always tempting to adjust and play with them. Patience if key.
They seem prone to fungal infections and poor handling during collection and often once they lose a single cell they just slowly errode to complete wipeout. Like I said I am no expert and I can keep them with reasonable stability so I would think anyone can. I run heavy on MH so I dont know how they fare for long term under PC but I dont think its enough.
