Flower Pot and Cup coral issues!!

[The Grizz]

So I have 2 flower pot's, 1 is red and the other is purple and a cup coral. When I first got them they all extended out and looked amazing but now the only time they seem to extend is when the light's go out and the moon light led's come on.

Any one have any ideas of what might be happening or what I should try to bring them around? They are not dead as I can see the polyp's ( if that is what they are called) in the hole's but they don't want to come out and play.

This is what they looked like for a few month's after I got them:




Can't seem to find a pic of the cup.
