Beth, there is no film on the surface of the coral just all around the stock. When i woke up this morning it looked like the stock had softened and the whole "head" of the coral was sitting on the rock. After about an hour of the halide being on it stood up again slightly and i can see the stock again. I figured a bad pic was better then nothing, so i got a couple with my webcam, which wouldnt reach, so i had to zoom in, so basically they are terrible pics i apologize. Hope it can help in some way though.
