Hey everyone - cut the guy some slack. He is asking for help here. Some have offered it and have given really good advice, but some are coming on just a tad bit strong.
The anemone is not necessarily dying. Anemones have one opening, and release waste through the same opening they take in food with. When they do this, they expel the water inside them. Then they take in more water, and re-inflate. In the second pic, it looks like it is doing just that.
The effectiveness of the lighting also depends on distance from that light. While 80w is not really all that much, supplementing with meaty foods regularly can help to counter not having enough light. Try squid chunks, silversides, scallop, etc...something meaty, several times a week. I also supplement with a liquid invertebrate formula every so often as well.
As to the lighting, IMO, you have more actinic than necessary. You have 1 - full actinic, and 1 50/50. The problem is the spectrum. True actinic is a good bulb to have, but a 50/50 only generally puts out 6000k intensity. I would personally replace one of those bulbs with a 10000k or 20000k bulb. Of course, ideally, a full upgrade would be best, but without that, at least increase your intensity.
There is one thing I have not seen asked, or given here. What are your water parameters like? Ammonia? Nitrites? Nitrates? Temp? pH? Alkalinity?
Also what kind of current do you have in the tank? Anemone's need current.
