I have my 70G tank cyclying for about 2 weeks with 30 pound cured LR from LFS, and 65 pound uncured LR. I have seen lots of worms, bugs and other live stuffs in the rock, especally when the light is switched from off to on. Most of them disapear immediately with light on. How can tell which one is good and which one is bad? Any website has pictures to tell all these small animals/lifes in the reef? I have no fish in the tank now.
