Hmmm, IMO, Bubble Tipped Anemone can handle a very wide variety of lighting, from the lower performance PC lighting, to T5s, to MH, with no problems at all. I kept one under PC lighting, for 4 years and it was healthy and beautiful. Now, that same RBTA has been under 10X54 T5HO lighting, for about 2 years, very happily. Splits, from my RBTA, are being kept under 400MH, in other people's tanks, with no issues at all.
Lee, you mention that you're dosing "about 15" different things. What are you dosing? Are you testing for it? Why are you dosing it? In my opinion, if you aren't able to answer all of these, you shouldn't be dosing it. I'm not saying you shouldn't be dosing, but make sure you're able to test for everything you dose. Make sure you know WHY you're dosing everything you dose and why/how your tank benefits from it. For instance, Iodine... IMO, dosing Iodine is a waste of time....lol.
Now, onto the next issue...FLOW. What kind of flow is your nem getting?
One other thought. You mentioned that you turned off your LEDs, to take pics, and it puffed up. Did you also turn off any flow?
