Well I came home tonighgt and my clarkiis pushed my coral off the rock and were what seemed tyo be sleeping on the rock where they had pushed the coral off of. When they sleep they lay down on the rock right? I was kinda scared because one of the fish was leaning and the other was upright, but I moved the rock around alittle and fixed the coral and they seemed to become alive again, I was just wondering if when they sleep they will lean against things?
