I know, I know, however Watts per gallon is a rather lousey rule of thumb here in regards to anemonies. I believe mine survive do to there being in the upper third of my aquarium. I have five on one rock that just never seem to move. These are getting much more punch on the par value of my lights.
I am also running VHO 2 - 12,000k super actinic and 2 - actinic bulbs.
Now I said that I would like to see them thrive better and to do that they would truly need more lights. Thats yours and mine.
Now I'm no expert on par value but your 130 watts would have less par value than my 380 watts. In my case they become much less effective at about 12 inches deep in my aquarium which is 24 inches deep. I'm not sure about your PC's. In my humble opinion corals love the 420nm of the blue actinic bulb of which I have 190 watts in those two blubs, add to that the super actinic 50/50's.
To make this shorter with my BTA's being in the upper 1/3rd of the tank they are enjoying almost all of the 380 watts, this is why I have been successful with them. I simply wish you the same luck.
With regards to lighting more is usually better, par value is more than half the battle, water clarity is also important for light penitration, water quality for health, skimmer for oxygenating the water.
Perhaps Bang or Kip can explain lighting better than I can, but 130 watts seems rather low to me.
All in all I think you are off to a fair chance at making him survive and healthy again. If possible I would plan (like I have been) on upgrading the lighting if possible. In your case lets start out by feeding 2 times per week and then after a month try 3 and see if there is a big difference.
BTA's and RBTA;s are one of the lesser light requiring anemonies. Lets hope that your sucess has been as good as mine has been.

This is a pic just after two of them split, the two front ones are obvious, the two in the middle look like one still but are two, there is a fifth just to the left back of the rock.
