Very interesting read. I'm well aware that it is dying slowly, just didn't think I could do anything about it since I have no reefers near me that would be able to house it. But after that read, I'm now thinking back when it was doing well...when I did not have a skimmer on my reef tank and I had algae problems... It sounds to me that it just likes a dirtier water, to which I'm pretty convinced that several soft corals are the same way.
I do have a light on my sump, though it is not currently on as I dismantled the fuge since my skimmer is way oversized for my current system in preperation for an eventual upgrade. The bulb is a 40 watter...so that would def need to be upgraded and there isn't any substrate in there...but it is "dirtier" overall in the sump with some algae growth in spots. I just don't think that putting it in the sump would solve the problem since it just seems to me like a water quality issue to me. If I'm off in left field with how I'm taking the issue, feel free to correct me. That tied in with having it go from my radions to a clip on work light would be just as deadly to it to me.
Inspiring article though, I would love to be able to keep one of these guys successfully. Sorry OP if I'm stealing the spotlight for a sec.
