Okay I am set up and introduced a clean up crew. When I look really close I see little bug like things crawling around the substrate. I think these are different sorts of pods that came on the live rock. There is one type that is quite a bit larger and looks similar to a grain of rice? it remains stuck to the glass side, and I am hoping this is a good pod not a bad one. The others are very small about the size of a flea and seem to hop around much like a flea. I sure hope these are good things and not bad........
