For the second time in over 2 years with my tank after at least an hour of darkness, I turned on the moon lights to see 1 gazillion bugs swimming all over the place and the shrimp and Blue Reef Chromis going nuts tying to eat them all. They were very small but seemed like little tadpoles. Battery died the instant I held the camera up -\-of course. The water was filled with them every square centimeter. A couple hours later I looked and they were completely gone. The corals were chowing on them.
