I have never seen this before in the past 6 - 7 years of reefkeeping. My wife was looking at the tank after lights out with her flashlight and saw two emeralds near each other. She said they were acting wierd so I took a look and they were releasing babies! I had no clue they were live bearere as well so I watched the little ones swimming around in the current. Such a cool sight to see. Here's a pic, best I could get with my camera
