I've just gotten a green tree frag from a friend and so it's just recently been fragged and cut. I've got it attatched via elastic to a small peice of liverock. At first the frag looked really good, bounced back really quickly and had spread out it's "limbs" like it was originally...not exactly, but promising. But now it's kinda started to droop, it started near the end of the photoperiod so i'm wondering if it's normal for the leather to droop at night, or if it's just normal reaction from being fragged, or if it's strange?
