I have been keeping an eye on my frags and some look nice and open, and some look like there closed and there getting skinny. I just turned the lights on so some of them are not open, but the ones i put a red circle around are what i am worried about. They are gettin very slim and never open. I also see TONS and TONS of small little centipedes crawling all over the rocks and corals. They are like a white/clear centipede and so small they are hard to see. I would say there about 1/4 of the size of a fenel seed. I am not sure if there harmful but they are so small i cant even take a picture of them. They are not red either, not even tinted, jsut clear/white.
