No matter where you place the anemone, I still say "not enough lighting". First off, you can't really control where an anemone goes...they go where they feel most comfortable. Secondly, the fixture that you have isn't the best but should be enough lighting to maintain most soft corals, but not anemones.
The "blue bulbs" that came with your system are not true actinics. They are simply painted to have the blue hue to them. You might research the cost of new actinic bulbs.
