I'm afraid I'm certainly no anemone expert, but we're definitely going to need some more specifics on your tank, especially your water. What exactly do you mean by full spectrum. Except actinic, I believe all lights are full spectrum. Is it HO, VHO, T-5 (I'm guessing not the latter). 69 watts probably isn't quite enough to keep an anemone happy, even in a 30 gallon. What are your water parameters, especially your nitrite, nitrate and phosphate levels (I'm assuming your ammonia is 0). What is your salinity water temperature and PH? Do you use natural filtration. . .specifically, live sand and/or rock?
Anemones are difficult to keep. I've know been struggling with mine over the couple of months I've had it. Unfortunately, we really know very little about these creatures except it doesn't take much to upset them. Just as a point of reference, you're going to want to your ammonia and nitrite levels absolutely undetectable, and your phosphate and nitrate levels at least very close to undetectable. Most people have told me they like higher salinity levels and temperature, so keep your specific gravity up around 1.025 (can't remember what salinity that equates to off the top of my head) and your temperature in the high 70s to very low 80s. If you haven't had your tank up and running at least 6 months, you'd be doing the anemone and yourself a favor taking it back. Anemones will deflate from time to time to expel wastes, but I've never seen anything actually come out of mine. I've heard some people talk about white stringy stuff coming out of their anemones which is in fact their guts, and it tends to happen right before the anemone starts to die.
I'm sure you'll get much better and more in depth advice from the more experienced people in this forum, so I'll end with that. Good luck.
