Sun Coral help.

[silentcivilian]

Ok... So i got this sun coral.. cause I wanted to try a non-photo coral, I enjoy the way they look, and dont mind taking the time to feed them. Trouble.. it doesnt come out at night.. It tried to for awhile.. but never really came all the way out.. but then again.. its never really fully retreated into its shell as in its giving up in life.. wondering what to do??

Tank water seems fine, nothing else having problem, zoos, pallies, hammer, acans, greenstar, birdsnests, brain, slimer, ricos and yuma all doing well. Ive even got in the habit at night of taking jucies.. target spraying the colony with the juices to bait them out.. but to no prevail.. how little light do they need.. Ive moved from low and sheltered with no light and little flow to higher up and higher flow with only light from my coralight 1watt LED nightlite coming down on it. I know they are light sensitive.. will I have to kill all light?? Cause I currently love the glimmer of my nightlite..

Advice??
