Part of your challenge will be to get it to acclimate to your lighting with dying. It needs bright light to get its zooxanthellae back, but while it is bleached it will try to hide from light that is too bright. Hence all the stories you hear about people with bleached anemones that crawl back into the rockwork and die.
Try feeding it SMALL bits of food and see how it responds. If it takes food, wait at least 48 hours before feeding it again. Many people overfeed and stress their anemones even further - give it plenty of time to eat and digest. An anemone is mostly water and doesn't need a lot of food to survive for LONG periods of time.
Otherwise, the anemone looks healthy. Your challenge will be getting it accustomed to your lighting (which is plenty bright, btw). I have seen people keep BTA's under normal output actinic bulbs in the past (though they were up at the top of the tank).
