Acans not expanding

BigH55

I'm that guy
Got some acans Friday. They opened and looked great the first day, they haven't opened since. I dont notice any die off and they have plenty of color. Is this normal?
 
mine are on bottom out in open, what kinda lights you have on tank. most of time they extend there sweeper tentacles at night but should have the colored part of tissue expanded. the ones i got from beldts look so so, but the ones from frag swap look real good and heathy so sometimes makes a difference were they come from.
