Green Carpet Anemone on the move.

Last night my green carpet anemone decided to move to another location in the tank. I bought him a couple of weeks ago from dmz94. It is my understanding that he had him for about 15 months. He looks great and eats well. He does take up a lot of room but thats ok. He settled in very nicely up against the side of the tank and planted himself in the sand well. Last week I purchased a Nova T5 actinic light. Would that cause him to move? Everything else has remained the same. I have 2 x 250 halides. I thought they liked a lot of light. The location he moved to is kind of shaded. He was rather cool to watch walk across the tank though.
Any way I was wondering if anyone had any ideas on why he decided to move.

thanks

Whats your light schedule? How much flow? Has there been any water parameter changes?

actinic 7am to 10pm. halides 10am to 8pm. no water parameter changes. I drip half a gallon of kalk once a day. The tank is a 90 gallon. Flow is comprised of a mag 9.5 and 3 300gph powerheads.
