Open is a good thing.
Most corals open up to feed (on light, phytoplankton, or both), and close up to "sleep" or protect themselves when stressed.
Some corals, like candy canes and bubbles, will "open" after dark and send out a mass of feeding tentacles.
Is there any ambient light in the room?
My xenia will open up long before the tank lights come on if there's enough light/sunlight in the room.

That sounds good.
They like low to moderate flow.
If they're in too heavy a flow they won't be able to stretch out and get the full benefit of the available light.
Anyway, just give your little guys some time to adjust and get on a regular schedule, and everything should be happy, happy.
