I have a nice Sinularia finger leather coral. I cut it myself several months ago and now, under new lighting, it has drastically changed color and only opens up nicely when the lights are off. Under my t5's it is a brilliant green and flows nicely, no problems being open all the time. But the frag I cut awhile back, I moved to a different tank under LEDs' The coral has been growing slowly but changed color to bright yellow. It also only opens up at nighttime. When the lights first come on for the day, it looks awesome! But about a half hour later, it is all closed up for most of the daytime. Still yellow, but people have even mistaken it for an Acro because it looks all lumpy and hard. thoughts?
